Crystal structure and Hirshfeld surface analysis of 2-{[2,8-bis­­(tri­fluoro­meth­yl)quinolin-4-yl](hy­dr­oxy)meth­yl}piperidin-1-ium 2-hy­dr­oxy-2-phenyl­acetate hemihydrate

The asymmetric unit of the title salt, C₁₇H₁₇F₆N₂O⁺·C₈H₇O₃⁻·0.5H₂O, comprises a pair of pseudo-enanti­omeric (i.e. related by a non-crystallographic centre of symmetry) piperidin-1-ium cations, two carboxyl­ate anions and a water mol­ecule of crystallization. The cations have similar conformations approximating to a letter, L: one of them shows disorder of its –CF₃ group over two sets of sites in a 0.775 (3):0.225 (3) ratio. Distinctive conformations are found for the anions, one with the carboxyl­ate group lying to one side of the plane through the phenyl ring and the other where the oxygen atoms lie to either side of the plane. In the latter, an intra­molecular hy­droxy-O—H⋯O(carboxyl­ate) charge-assisted hydrogen bond is found. The packing features extensive O—H⋯O,N hydrogen bonding, often charge-assisted; C—H⋯π inter­actions are also formed. The hydrogen bonding results in the formation of five distinctive supra­molecular synthons and assembles mol­ecules in the ac plane. The quinolinyl rings lie to either side of the layer and inter-digitate with layers on either side, are approximately parallel to the b axis and are connected by π–π [inter-centroid separation = 3.6904 (18) Å] as well as C—F⋯π(quinolin­yl) inter­actions to consolidate the three-dimensional crystal. The dominance of the conventional hydrogen bonding in the mol­ecular packing is confirmed by an analysis of the Hirshfeld surface.

1. Chemical context

When the racemic compound mefloquine is reacted with HCl, protonation occurs at the piperdinyl-N atom to yield the [(R*,S*)-(2-{[2,8-bis­(tri­fluoro­meth­yl)quinolin-4-yl](hy­droxymeth­yl)piperidin-1-ium chloride salt; see Scheme for the chemical diagram of the cation, also known as mefloqinium. This salt, racemic erythro-mefloquine hydro­chloride, has been used as an anti-malarial drug since 1971 (Maguire et al., 2006). As an example of drug re-positioning, new biological activities have been sought for this drug and derivatives resulting in the disclosure of their potential as, for example anti-bacterial (Mao et al., 2007), anti-mycobacterial (Gonçalves et al., 2012) and anti-cancer (Rodrigues et al., 2014) agents. This inter­est notwithstanding, it turns out that the crystal chemistry of the cation is rich and diverse. For example, the crystal structures of salts of the cation with three isomeric n-nitro­benzoates (n = 2, 3, and 4) have been described where the supra­molecular association led to chains in each case, but these were sustained by distinct hydrogen-bonded synthons (Wardell et al., 2011).

In addition, recently, two kryptoracemates have been revealed, namely in mefloqinium salts with p-fluoro­benzene­sulfonate (Jotani et al., 2016) and (+)-3,3,3-tri­fluoro-2-meth­oxy-2-phenyl­propanate (Wardell et al., 2016). It was in this context that the title hydrated salt, (I), was investigated: this was isolated after racemic mefloquine was reacted with a stoichiometric amount of racemic 2-hy­droxy-2-phenyl­acetic acid. Herein, the crystal and mol­ecular structures of the title salt, (I), are described as well as a Hirshfeld surface analysis.

2. Structural commentary

The asymmetric unit of (I) comprises two 2-{[2,8-bis­(trifluoro­meth­yl)quinolin-4-yl](hy­droxy)meth­yl}piperidin-1-ium cations, two 2-hy­droxy-2-phenyl­acetate anions and a water mol­ecule of crystallization. The cations, Fig. 1, are pseudo-enanti­omeric (i.e. related by a non-crystallographic inversion centre) with the N1-cation having an S-configuration at the C12 atom and an R-configuration at C13 and therefore being assigned as the [(−)-erythro-mefloquinium] cation. The N3-cation, with chirality at the C29 and C30 atoms being R and S, respectively, is assigned as [(+)-erythro-mefloquinium]. As anti­cipated, protonation during crystallization leads to a piperidin-1-ium cation, as confirmed by the pattern of hydrogen bonding, which is discussed below in Supra­molecular features. Each cation comprises an essentially planar quinolinyl residue attached to a piperidinium residue (with a chair conformation) via a methine link. The dihedral angle between the quinolinyl-NC₅ ring plane and the best plane through the piperidinium ring is 71.91 (16)° indicating an almost perpendicular relationship so that the cation adopts an L-shape; the equivalent dihedral angle for the N3-cation is 80.58 (17)°. This assignment is also supported by the values of the C2—C3—C12—C13 and C19—C20—C29—C30 torsion angles of −100.4 (3) and 108.1 (3)°, respectively. The hydroxyl-O and piperidinium-N atoms lie to the same side of the piperidinium ring, being gauche across the methine-C—C(methine) bond with N2⋯O1 = 3.019 (4) Å and O1—C12—C13—N2 = 73.3 (3)° for the N1-cation; the equivalent values for the N3-cation are 2.931 (4) Å and −70.7 (3)°, respectively. The similarity in the two cations is emphasized in the overlay diagram shown in Fig. 2 where the inverted form of the N3-cation has been superimposed upon the N1-cation.

Figure 2 An overlap diagram highlighting the similarity of the conformations of the first (red) and inverted second (blue) independent cations. The cations have been overlapped so the the quinolinyl rings are coincident.

The anions in (I), Fig. 3, were modelled with the N1-anion having an S-configuration at the C36 atom and an R-configuration at atom C44 of the second independent anion. The confirmation of deprotonation is found in the near equivalence of the C35—O3, O4 [1.260 (4) and 1.263 (4) Å] and of the C43—O6, O7 [1.223 (5) and 1.246 (5) Å] bond lengths. As evidenced from the overlay diagram shown in Fig. 4, which overlaps the inverted form of the O6-anion with the O3-anion with phenyl rings made coincident, major conformational differences between the anions exist. In the O3-anion, the dihedral angle between the phenyl ring and carboxyl­ate group is 71.2 (3)° which is a little more acute than the comparable angle of 78.4 (4)° for the O6-anion. However, the significant difference arises in the relative dispositions of the carboxyl­ate group to the phenyl ring, lying completely to one side of the ring for the O3-anion but with one carboxyl­ate-O atom above and the other below the plane through the phenyl ring for the O6-anion. This difference is qu­anti­fied in the disparity in the C35—C36—C37—C38 and C43—C44—C45—C46 torsion angles of 108.0 (3) and 20.0 (6)°, respectively. Another difference is noted in the formation of an intra­molecular hy­droxy-O—H⋯O(carboxyl­ate) hydrogen bond in only one of the anions. In both cases the hy­droxyl O atoms is to a first approximation syn to a carboxyl­ate-O atom as seen in the O3—C35—C36—O5 and O7—C43—C44—O8 torsion angles of 151.9 (3) and 17.3 (6)°, respectively. However, it is only in the O6-anion that the aforementioned hydrogen bond is formed to close a five-membered {⋯HOC₂O} loop, Table 1.

3. Supra­molecular features

In addition to considerable conventional hydrogen bonding, often charge-assisted, there are other inter­molecular inter­actions at play in the mol­ecular packing (Spek, 2009). The geometric parameters characterizing most of these inter­molecular inter­actions are given in Table 1. The pattern of hydrogen bonding clearly differentiates both the cations and in the same way, the anions. Thus, the hy­droxy group of the N1-cation forms a charge-assisted hy­droxy-O—H⋯O(carboxyl­ate) inter­action with an anion, while the hydroxyl group of the N3-cation forms a hy­droxy-O—H⋯O(hy­droxy) link between the cations. The piperidinium-N—H₂ H atoms of the N1-cation forms charge-assisted hydrogen bonds to the water mol­ecule of crystallization and to the O3-carboxyl­ate atom, whereas those of the N3-cation inter­act with the hy­droxy-O8 and carboxyl­ate-O4 atoms.

A different hydrogen-bonding pattern is also noted for the anions, already differentiated by the formation of an intra­molecular hy­droxy-O—H⋯O(carboxyl­ate) inter­action in the O6-anion. The hy­droxy group of the O3-anion forms a hy­droxy-O—H⋯O(carboxyl­ate) link between the anions. Both carboxyl­ate-O3, O4 atoms accept hydrogen bonds from piperidinium-N—H H atoms whereas the carboxyl­ate-O5, O6 atoms form inter­actions with piperidinium-N—H and anion–hydroxyl-H H atoms, respectively. The carboxyl­ate-O3 and O7 atoms each form two hydrogen bonds with the additional inter­actions involving water-H atoms. Finally, as just mentioned, the water mol­ecule forms two donor inter­actions with carboxyl­ate-O atoms, accepts a hydrogen bond from a piperidinium-N—H H atom and also accepts a contact from a quinolinyl-C—H atom.

The just described hydrogen bonding gives rise to a number of cyclic synthons. Referring to Fig. 5a, the largest synthon is sustained exclusively by O—H⋯O hydrogen bonding, being a centrosymmetric 22-membered {⋯OCO⋯HOH⋯OC₂OH}₂ ring. Four other rings are formed mediated by hydrogen bonding but the only remaining centrosymmetric synthon features two bridging piperidinium-N—H H atoms, which link water- and carboxyl­ate-O atoms to generate a 12-membered {⋯HNH⋯OH⋯O}₂ synthon. The three remaining synthons do not have symmetry. The smallest, nine-membered {⋯HNC₂OH⋯OCO} abuts the 12-membered synthon just described and shares a common N—H bond. The nine-membered synthon is connected on the other side by an 12-membered ring featuring the second piperidinium-N—H₂ group, i.e. {⋯HNC₂OH⋯OH⋯OC₂O}. Portions of both of the nine- and 12-membered synthons participate in the formation of a larger 15-membered synthon which involves both piperidinium-N—H₂ groups, i.e. {⋯HNH⋯OC₂O⋯HNH⋯OH⋯O⋯HO}; one of the O—H⋯O links is the intra­molecular hy­droxy-O—H⋯O(carboxyl­ate) hydrogen bond. A tight methyl­ene-C—H⋯π(anion-phen­yl) inter­action is also noted, Table 1. The hydrogen bonding extends laterally in the ac plane with the quinolinyl residues lying to either side in the b-axis direction and in orientations enabling inter-digitation. Inter­actions between rings are of the type π–π, occurring between quinolinyl-bound (C21–C26) and (N1,C1–C4,C9)ⁱ rings with an inter-centroid separation of 3.6904 (18) Å and angle of inclination of 8.70 (15)°; symmetry code (i): 1 − x, 1 − y, 1 − z. A variety of C—F⋯π(quinolin­yl) inter­actions provide additional links in the inter-layer region. A view of the unit-cell contents is shown in Fig. 5b.

4. Hirshfeld surface analysis

Crystal Explorer (Wolff et al., 2012) was used to generate Hirshfeld surfaces mapped over d_norm, shape-index, curvedness and electrostatic potential. The electrostatic potentials were calculated using TONTO (Spackman et al., 2008; Jayatilaka et al., 2005) integrated into Crystal Explorer; the crystal geometry was used as the input. The electrostatic potentials were mapped onto Hirshfeld surfaces using the STO-3G basis set at the Hartree–Fock level of theory. The contact distances d_i and d_e from the Hirshfeld surface to the nearest atom inside and outside, respectively, enables the analysis of the inter­molecular inter­actions through the mapping of d_norm.

The Hirshfeld surfaces mapped over d_norm for the N1-cation, N3-cation and the entity comprising the two anions together with the water mol­ecule of crystallization are illustrated in Fig. 6, and Hirshfeld surfaces mapped over electrostatic potential for the same species, in the ranges −0.25 to +0.17, −0.26 to +0.17 and −0.14 to +0.20 au, respectively, are illustrated in Fig. 7. The mapping of Hirshfeld surfaces over d_norm in the range −0.5 to +1.3 au reveals potential hydrogen-bond donors and acceptors as bright-red spots. The further mapping of Hirshfeld surfaces over d_norm in the range −0.1 to +1.1 au results in faint-red spots on the surfaces which can satisfactorily describe the influence of other inter­molecular inter­actions in the crystal such as C—H⋯O, C—H⋯F, C—H⋯π, C—F⋯π and π–π stacking. The bright-red spots appearing near the donor hydroxyl-H2O, Fig. 6c, and acceptor hydroxyl-O1O atom, Fig. 6a, show the O—H⋯O link between the two independent cations. The charge-assisted O—H⋯O inter­action between the hydroxyl-H1O and carboxyl­ate-O4 atoms can be viewed as bright-red spots in Fig. 6a and 6f, respectively. The bright-red spots at the piperidinium-H1N and H2N atoms, Fig. 6a, and oxygen atoms O3, Fig. 6e, and O1W, Fig. 6f, indicate the formation of N—H⋯O hydrogen bonds associated with the N1-cation. The other group of N—H⋯O bonds resulted from piperidinium-H3N and H4N of the N3-cation and are apparent as the bright-red spots on the surface donors, Fig. 6c, and acceptors, Fig. 6f (i.e. carboxyl­ate O4 and O8), respectively; the faint-red spots near the piperidinium-N4, Fig. 6c, and carboxyl­ate-O4 atoms, Fig. 6e, are due to the presence of comparatively weak N—H⋯O hydrogen bonds. The existence of water-O—H⋯O hydrogen bonds can be viewed as bright-red spots near the H2W and carboxyl­ate-O3 atoms while the other is indicated with dashed lines in Fig. 6e. Finally, the bright-red spots at hydroxyl-H5O, Fig. 6f, and carboxyl­ate-O6, Fig. 6e, provides a link between the anions through O—H⋯O inter­actions.

Figure 7 View of Hirshfeld surfaces mapped over electrostatic potential for (a) the N1-cation (b) the N3-cation and (c) the anions and water mol­ecule.

The faint-red spots near the fluorine atoms of the CF₃ groups of the cations indicate their participation in various inter­molecular inter­actions. The faint-red spots near the F1, F7 and F11 atoms shown in Figs. 6a, 6c and 6d, indicate short inter­atomic F⋯F contacts, Table 2. The spots near the F2 and piperidinium-C17 atoms arise form inter­molecular C—H⋯F inter­actions, Fig. 6b and Table 2. The presence of C—F⋯π inter­actions are evident from the diminutive-red spots near the F4 and F5 atoms of the N1-cation, and F8 of the N3-cation, Figs. 6a, 6b and 6d, and from the short inter­atomic C⋯F contacts listed in Table 2. The Hirshfeld surfaces mapped with shape-index properties are illustrated in Fig. 8 and reflect these C—F⋯π inter­actions. In addition to above, the short inter­atomic C48⋯F7 contact is also viewed as very faint-red spots near these atoms on the surface, Figs. 6c, 6d and 6e. The faint-red spots present near the methyl­ene-C14—H, Fig. 6b, and anion-phenyl-C42 atoms, Fig. 6e, and short inter­atomic C⋯H/H⋯C contacts between methyl­ene-H14A and anion atoms C37, C41 and C42, as summarized in Table 2, clearly indicate their contribution to the C—H⋯π inter­action described above. The presence of a C—H⋯O inter­action between piperidinium-C31—H of the N3-cation and hydroxyl-O8 of one of the anions is observed as diminutive-red spots near these atoms in Figs. 6c and 6f, and qu­anti­fied in Table 2. In addition to the above inter­molecular inter­actions related to C⋯H/H⋯C contacts, the short inter­atomic contacts between the anion-C46 and C35 atoms, Figs. 6e and 6f, and N1-cation hydrogens H6 and H15A, Figs. 6a and 6b, are also viewed as faint-red spots near these atoms. The immediate environments about the N1- and N3-cations and the anions and water mol­ecule within the d_norm-mapped Hirshfeld surface mediated by the above inter­actions are illustrated in Fig. 9.

The combination of d_i and d_e in the form of two-dimensional fingerprint plots (McKinnon et al., 2007) provides a summary of the inter­molecular contacts occurring in the crystal. The overall two-dimensional fingerprint plot for (I) and those delineated into H⋯H, O⋯H/H⋯O, C⋯H/H⋯C, F⋯H/H⋯F, F⋯F, C⋯F/F⋯C and C⋯C contacts (McKinnon et al., 2007) are illustrated in Fig. 10a–h, respectively; their relative contributions are summarized in Table 3. The fingerprint plot delineated into H⋯H contacts, Fig. 10b, shows that although these make the greatest contribution to the overall Hirshfeld surface, i.e. 31.2%, its comparatively low value is due to the involvement of many of the available hydrogen atoms of the various functional groups in specific inter­molecular O—H⋯O and N—H⋯O hydrogen bonds. A nearly symmetric (mirror) distribution of points reflected as a saw-tooth with the tips at d_e + d_i ∼2.1 Å correspond to a short inter­atomic piperidinium-H1O⋯H2O contact between hydroxyl-hydrogens of the two independent cations, Table 2; the other short inter­atomic H⋯H contacts, Table 2, are associated with the points distributed in (d_e, d_i) region less than the van der Waals separations, i.e. 2 × 1.2 Å. The 19.2% contributions from O⋯H/H⋯O contacts to the overall surface results from inter­molecular O—H⋯O, N—H⋯O and C—H⋯O inter­actions as well as short inter­atomic O⋯H/H⋯H contacts in the crystal, Table 2. In the fingerprint plot delineated into O⋯H/H⋯O contacts, Fig. 10c, a pair of long spikes having tips at d_e + d_i ∼1.7 Å and the appearance of green points aligned as a pair of streaks are due to the presence of dominant O—H⋯O and N—H⋯O hydrogen bonds.

The fingerprint plot corresponding to C⋯H/H⋯C contacts, Fig. 10d, show a fin-like distribution of points with the edges at d_e + d_i ∼2.6 Å resulting from the presence of C—H⋯π inter­actions and short inter­atomic C⋯H/H⋯C contacts, as summarized in Table 2. The presence of a pair of two small peaks at d_e + d_i ∼2.7 Å and 2.8 Å in a tube-shaped distribution of points in the fingerprint plot delineated into F⋯H/H⋯F contacts, Fig. 10e, arise from short inter­molecular F⋯H/H⋯F contacts, Table 2. The presence of two tri­fluoro­methyl groups in each cation increases the percentage contribution from these contacts to the Hirshfeld surface to 23.1%, thereby contributing to the reduced relative contribution from H⋯H contacts. In the fingerprint delineated into F⋯F contacts, Fig. 10f, the distribution of points in a pencil-tip shape with the tip at d_e + d_i ∼2.8 Å represent the short inter­atomic F⋯F contacts listed in Table 2. The inter­molecular C—F⋯π and C⋯F inter­actions in the crystal are characterized by a fin-shape, at d_e + d_i ∼3.0 Å, in the fingerprint plot delineated into C⋯F/F⋯C contacts, Fig. 10g, and make a 4.6% contribution to the surface. A small 2.3% contribution from C⋯C contacts to the Hirshfeld surface with the parabolic distribution of points, Fig. 10h, around the (d_e, d_i) distances slightly shorter than their van der Waals radii, i.e. 2 × 1.7 Å, indicate π–π stacking inter­actions between quinolinyl rings. The presence of π–π stacking inter­actions between the symmetry-related rings is also indicated through the appearance of red and blue triangle pairs on the Hirshfeld surface mapped with shape-index property identified with arrows in the images of Fig. 11, and in the flat regions on the Hirshfeld surfaces mapped over curvedness in Fig. 12.

Figure 11 Views of Hirshfeld surfaces mapped over the shape-index for the (a) (N1,C1–C3,C9) and (b) (C21–C26) rings, highlighting π–π stacking.

5. Database survey

Recent contributions to the structural chemistry of mefloqinium salts (Jotani et al., 2016; Wardell et al., 2016) have included tabulated summaries of related literature structures and key geometric parameters. The cations in (I) conform to expectation. Two recently determined structures are particularly noteworthy as they exhibit kryptoracemic behaviour, i.e. contain enanti­omeric species that are not related by crystallographic symmetry, meaning they crystallize in one of the 65 Sohncke space groups, which lack inversion centres, rotatory inversion axes, glide planes and mirror planes. This phenomenon is rare for organic species, occurring in just 0.1% of their structures (Fábián & Brock, 2010). The two kryptoracemates arise for different reasons. In the first example, the ortho­rhom­bic (P2₁2₁2₁) crystals isolated from the 1:1 reaction of mefloquinium chloride and p-fluoro­benzene­sulfonyl chloride in the presence of NaOH (Jotani et al., 2016), contained [(+)-erythro-mefloquinium] and [(−)-erythro-mefloquinium] cations as well as a chloride and p-fluoro­benzene­sulfonate anions to provide the charge balance. The second example was isolated from the attempted chiral resolution of mefloquine with the carb­oxy­lic acid, 3,3,3-tri­fluoro-2-meth­oxy-2-phenyl­propanoic acid, i.e. (+)-PhC(CF₃)(OMe)CO₂H. Crystallography showed the triclinic (P1) crystals to comprise the [(+)-erythro-mefloquinium] and [(−)-erythro-mefloquinium] cations with two independent (+)-3,3,3-tri­fluoro-2-meth­oxy-2-phenyl­propanate anions. Hence, different anions appear to have promoted kryptoracemic behaviour in the chloride/p-fluoro­benzene­sulfonate salt (Jotani et al., 2016) and distinctive crystal packing is responsible for this behaviour in the (+)-3,3,3-tri­fluoro-2-meth­oxy-2-phenyl­propanate salt (Wardell et al., 2016). The latter reason seems to apply in the case of (I) where a non-crystallographic symmetry relationship exists between the cations. However, (I) being centrosymmetric indicates that kryptoracemic-type behaviour for the mefloquinium cation is not limited to non-centrosymmetric structures.

6. Synthesis and crystallization

Solutions of mefloquine (1 mmol) in MeOH (15 ml) and ()PhCHOHCO₂H (1 mmol) in MeOH (10 ml) were mixed at room temperature. The reaction mixture was set aside at room temperature for three days and the resulting colourless slabs collected; M.pt: 434–346 K. IR (KBr disc): 3400–2100 (v br), 1586, 1313, 1190, 1130, 739 cm^{−1. 13}C NMR (100 MHz, d₆-DMSO): δ 21.74, 22.01, 22.38, 44.54, 59.25, 68.39, 73.45, 115.43, 121.22 [J(C—F) = 273.6 Hz], 123.69 [J(C—F) = 272.2 Hz], 126.34, 126.38, 126.52, 127.19 [J(C—F) = 291.3 Hz], 127.53, 128.11. 129.05, 129.76 [J(C—F) = 4.7 Hz], 142.74, 143.03, 146.64 [J(C—F) = 34. 0 Hz], 151.82, 175.75 p.p.m.

7. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 4. The H atoms were geometrically placed (C—H = 0.95–1.00 Å) and refined as riding with U_iso(H) = 1.2U_eq(C). The O- and N-bound H atoms were located from difference maps but, refined with O—H = 0.84±0.01 Å and N—H = 0.88±0.01 Å, and with U_iso(H) = 1.2U_eq(N) and 1.5U_eq(O). One reflection, i.e. (1), was omitted from the final refinement owing to poor agreement. The C27-CF₃ group was modelled as being disordered over two orientations with a site occupancy ratio 0.775 (3):0.225 (3). The anisotropic displacement parameters for pairs of F atoms were constrained to be equal and restrained to be nearly isotropic. Even so, one atom in particular showed elongated displacement ellipsoids, i.e. the F8 atom, but this was not modelled further. Multiple atomic positions were not discerned for the O6-anion, Fig. 3b. Finally, the maximum and minimum residual electron density peaks of 1.75 and 0.66 eÅ⁻³, respectively, were located 0.84 Å and 0.35 Å from the H44 and O7 atoms, respectively. Given the strong and directional hydrogen bonding in this region of the mol­ecule, it is likely that the large residual is an artefact of the data.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
