The protonated analogue of benzamidine is of special interest in forming strong intermolecular hydrogen bonds, as its amidinium group exhibits ideal properties for coupling with carboxylate groups in a crystal structure. The ability of these organic salts to aggregate readily through dimer heterosynthons via N+—H···O- (±)(CAHB) (charge-assisted hydrogen bonds with plus and minus charges on the donor and acceptor atoms, respectively; Gilli & Gilli, 2009), relies on ΔpKa [ΔpKa = pKa (conjugate acid of the base) - pKa (acid), where the pKa values are for aqueous solutions at 298 K]. Generally, a sufficiently large ΔpKa value (i.e. greater than 3) should result in a salt (Bhogala et al., 2005). With smaller ΔpKa values, a cocrystal can be expected, but that parameter seems inappropriate for accurately predicting salt or cocrystal formation in the solid state when 0 < ΔpKa < 3 (Portalone & Colapietro, 2009; Portalone, 2011a). This dimeric motif is commonly observed in biological systems between arginine and aspartic and glutamic acids (Saenger, 1984). To date, the only exception to the complementarity of the amidinium and carboxylate groups has been reported for benzamidinium isoorotate (2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate) (Portalone, 2010).
As a continuation of the systematic study carried out in this laboratory to test the robustness of the R22(8) hydrogen-bond synthon (Bernstein et al., 1995; Motherwell et al., 1999) formed by benzamidine with benzoic acid derivatives in a 1:1 ratio (Irrera et al., 2012), the molecular and supramolecular structures of three acid–base complexes formed by benzamidine with benzoic acids, namely benzamidinium 3-methoxybenzoate, (I), benzamidinium 4-methoxybenzoate, (II), and benzamidinium 3,4,5-trimethoxybenzoate monohydrate, (III), are reported. With pKa values of 11.6 for benzamidine (Hafelinger, 1975), 4.1 and 4.5 for 3- and 4-methoxybenzoic acids, respectively (https://research.chem.psu.edu/brpgroup/pKa_compilation.pdf [Is this available in a peer-reviewed form anywhere?]), and 4.2 for 3,4,5-trimethoxybenzoic acid (expected value based on two similar acids, namely 2,3,4- and 2,4,5-trimethoxybenzoic acid, both showing pKa = 4.24; Kazakevich & Lobrutto, 2007), for these acid–base complexes the ΔpKa falls in the range 7.1–7.5 and leads to the formation of molecular salts.
Salts (I)–(III) were obtained by the reaction of equimolar quantities (1 mmol) of benzamidine (Fluka, 95%) and 3-methoxybenzoic acid (Sigma–Aldrich, 99%), 4-methoxybenzoic acid (Sigma–Aldrich, 99%) and 3,4,5-trimethoxybenzoic acid (Sigma–Aldrich, 99%) dissolved in ethanol (20 ml). The reaction mixtures were heated under reflux at 323 K for 8 h and then, after cooling to ambient temperature, the solvent was removed under vacuum. The solid residues were recrystallized by room-temperature evaporation of hot-filtered water solutions to give, after 10 d, good X-ray diffraction quality colourless crystals.
Crystal data, data collection and structure refinement details are summarized in Table 1. H atoms were originally found in a difference Fourier map but subsequently treated differently. All C-bound H atoms were placed in calculated positions, with C—H = 0.97 (phenyl) or 0.95–1.00 Å (methyl), and refined as riding on their carrier atoms, with Uiso(H) = 1.2Ueq(C) for aromatic H atoms or 1.5Ueq(C) for methyl H atoms. The H atoms of the methyl groups were allowed to rotate with a fixed angle around the C—C bond to best fit the experimental electron density [HFIX 138 in the SHELXL program suite (Sheldrick, 2008)]. The positional and displacement parameters of the H atoms of the amidinium groups and of one of the two water molecules of (III) were freely refined, giving N—H distances in the range 0.85 (2)–1.00 (2) Å and O—H distances in the range 0.84 (3)–0.89 (3) Å. The O—H distances for the H atoms attached to atom O7 of the second water molecule of (III) were restrained to 0.90 (2)–0.99 (2) Å, and the H atoms were refined with Uiso(H) = 1.2Ueq(O7). It is worthy of note that, of the two H atoms attached to atom O7 (H71 and H72), only H72 participates in the formation of O—H···O hydrogen bonds.
Benzamidinium 3-methoxybenzoate (benzamH+.3mb-), (I) (Fig. 1), and benzamidinium 4-methoxybenzoate (benzamH+.4mb-), (II) (Fig. 2), both crystallize in the monoclinic space group P21/n, with one crystallographically independent dimer of monoprotonated benzamidinium cations (benzamH+) and benzoate anions (3mb- and 4mb-, respectively) in the asymmetric unit. The asymmetric unit of benzamidinium 3,4,5-trimethoxybenzoate monohydrate (benzamH+.345mb-.H2O), (III) (Fig. 3), which crystallizes in the monoclinic space group P21/c, is noticeably more complex than those of (I) and (II), and consists of two benzamH+ cations counterbalanced by two 345mb- anions, completed by two water molecules of crystallization (Fig. 3). The molecular structures of salts (I)–(III) are very similar with regard to interatomic distances and angles.
In the cationic substructures, where protonation takes place at the same site of the amidine group, the benzamH+ cations are not planar. The dihedral angles between the mean plane of the benzene ring and the amidinium group are in the range 30.7 (1)–42.3 (1)°, larger than the values observed in benzamidinium (2-acetamidobenzoyl)formate [16 (3)°; Joshi et al., 1994], benzamidinium acetylsalicylate [15.2 (2)°; Kolev et al., 2009] or the two polymorphic forms of benzamidinium 2,6-dimethoxybenzoate [20.2 (1), 14.4 (1) and 23.6 (1)°; Irrera et al., 2012]. For all compounds, this disposition is a consequence of the steric hindrance between the NH2 group and the benzene ring, as indicated by the N—C(ortho) contacts which are in the range 2.888 (2)–2.969 (2) Å, and it prevents conjugation between the amidinium group and the benzene ring. Indeed, the C—C(amidine) distances are in the range 1.472 (3)–1.484 (3) Å and compare well with the expected Csp2—Csp2 single-bond length of 1.482 (1) Å (Allen et al., 1987). This nonplanar conformation is commonly observed in small-molecule crystal structures, whereas in benzamidinium-containing structures in the Protein Data Bank (PDB; Berman et al., 2000) the most frequently encountered conformation is the planar one (Li et al., 2009). The C—N bond lengths are in the range 1.307 (2)–1.315 (2) Å, evidencing the delocalization of the π-electrons and double-bond character when compared with the corresponding bond lengths found in benzamidine [1.294 (3) and 1.344 (3) Å; Barker et al., 1996] and benzdiamidine [1.283 (2) and 1.349 (2) Å; Jokić et al., 2001].
In the anionic substructures, the benzene rings of salts (I)–(III) show small deviations from planarity, with a maximum deviation from the least-squares plane of the benzene ring in (I) of 0.019 (2) Å for atom C10, and the carboxylate groups are twisted with respect to the plane of the aromatic fragment by 22.3 (1)–31.3 (1)°. In these anions, the bond lengths and angles of the benzene ring are in accord with corresponding values obtained for both the orthorhombic and tetragonal forms of 2,6-dimethoxybenzoic acid (Portalone, 2009, 2011b), for 4-methoxybenzamidinium 2,6-dimethoxybenzoate (Portalone, 2012) and for benzamidinium 2-methoxybenzoate (Portalone, 2013). The C—O distances range from 1.252 (2) to 1.262 (2) Å, indicating that the carboxylate groups are deprotonated in the crystal structure. The methoxy groups attached at atom C13 in the 3mb- anion and at atom C14 in the 4mb- anion are nearly coplanar with the benzene ring, with C15—O3—C10—C9 and C15—O3—C11—C10 torsion angles of -7.7 (4) and -3.8 (2)°, respectively. In the 345mb- anion, the two methoxy substituents in meta positions with respect to the carboxylate group are coplanar with the benzene ring and force the remaining methoxy group to be almost orthogonal to the plane of the aromatic fragment [the twist angles between the benzene ring and the methoxy group in the para position are 74.1 (2) and 107.4 (2)°].
The most attractive aspect of the three structures resides in their hydrogen-bonding scheme, which is dominated by N+—H···O- (±)CAHB (Tables 2–4).
The ionic components of the three title molecular salts are strongly interlinked into a dimeric hydrogen-bonded structure with graph-set motif R222(8) by N+—H···O- (±)CAHB. Remarkably, at variance with the well known carboxylic dimer R22(8) motif, in these compounds the carboxylate–amidinium pairs are not planar. A difference in the rotation from the plane of the benzene rings of the amidinium and carboxylate groups results in a slight twist of the amidinium–carboxylate dimer [the dihedral angles for the planes defined by the CN2+ and CO2- atoms are in the range 8.8 (1)–14.2 (1)°]. Nonetheless, the interface is very stable, as indicated by the N+—H···O- parameters: N+···O- distances are in the range 2.751 (3)–2.892 (2) Å and N+—H···O- angles are in the range 161 (2)–180 (2)°. Larger deviations from planarity of the carboxylate–amidinium pairs have been reported previously for two concomitant polymorphs of the molecular salt of benzamidinium 2,6-dimethoxybenzoate (Irrera et al., 2012) and for benzamidinium 2-methoxybenzoate (Portalone, 2013), in which the CN2+/CO2- dihedral angles are in the range 18.6 (1)–29.5 (1)°.
The supramolecular structures of salts (I) and (II) are very similar and only the molecular arrangement of (I) is shown (Fig. 4). As mentioned previously, each subunit, built from the ion pairs of the asymmetric unit, forms a ring motif of the type R22(8) via the bidentate interaction of the N—H and C═O groups. These subunits then interact with adjacent ion pairs to form R64(16) rings through the remaining N+—H···O- hydrogen bonds, resulting in a corrugated-like plane approximately parallel to the ab plane.
The supramolecular structure of (III), in which the water molecules play a key role, shows a completely different arrangement of molecules through a diversity of noncovalent interactions. Eleven hydrogen bonds, namely four N+—H···O-, four N+—H···O and three Owater—H···O, involve all donor sites apart from atom O7, which remains partially unsaturated (Fig. 5). For descriptive purposes, it is convenient to select the asymmetric unit as the elemental building block of the crystal structure. In the asymmetric unit, the two R22(8) dimers, two water molecules and one para-methoxy group offer favourable dispositions to form hydrogen-bonded rings with a graph-set motif of R54(16). These hydrogen-bonded rings are further interconnected with symmetry-related rings by N+—H···O- hydrogen bonds, leading to the formation of tapes along the a axis. These tapes are then crosslinked by N+—H···O-, N+—H···Owater and Owater—H···O- hydrogen bonds into a two-dimensional network approximately parallel to the ac plane.
In conclusion, as only those synthons that occurr repeatedly in crystal structures are useful in crystal design (Nangia & Desiraju, 1998), the structures reported here further demonstrate the robustness of the benzamidinium cation as a (±)CAHB synthon with benzoic acids in two-component 1:1 salts. The strong primary electrostatic interaction between the two interfacial H atoms anti to the benzene ring, which mediate the two-point interaction between the benzamidinium cation and the carboxylate group, provides sufficient driving force for the directed assembly of binary molecular complexes, but interestingly leaves the remaining N+—H available for a variety of additional catenation of structural subunits. Indeed, due to the canting of the R22(8) heterosynthon, secondary N+—H···O- hydrogen bonds, external to the amidinium–carboxylate salt bridges, produce a different overall molecular disposition in the organic salts reported here and in benzamidinium 2-methoxybenzoate (1/1) (tape structure; Portalone, 2013), in both the 2/2 monoclinic and 1/1 orthorhombic forms of benzamidinium 2,6-dimethoxybenzoate (tape structures; Irrera et al., 2012), and in p-methylbenzamidinium benzoate (1/1) (channel-like structure; Kuzmenko et al., 2001). The complementary interactions in the R22(8) amidinium/carboxylate heterosynthon have been used to design layered magnetic materials, as in the case of the molecular salt 3-cyanobemzamidinium 2,2,4,4-tetramethylpyrroline-N-oxyl-3-carboxylate (Papoutsakis et al., 1999).
An extension of this study, aimed at creating three-component salts by reducing the ratio of benzamidine to acid so as to deprotonate only half of the acid molecules, and then observing how the un-ionized acid molecules can be incorporated into the supramolecular assembly, is currently under way in this laboratory.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |
