(E)-2-[2-(4-Carb­oxy­phen­yl)ethen­yl]-8-hydroxy­quinolin-1-ium chloride ethanol monosolvate

M. M. Schulze, W. Seichter and E. Weber

Abstract top

In the title compound, C18H14NO3+·Cl-·CH3CH2OH, the dihedral angle formed by the mean planes of the quinolinium and benzene rings is 3.4 (1)°, while the carb­oxy substituent is tilted at an angle of 4.8 (1)° with respect to the benzene ring. There is a short N-H...O contact in the cation. In the crystal, due to the planar mol­ecular geometry, two-dimensional aggregates are formed parallel to (221) via C-H...O, C-H...Cl, O-H...Cl and N-H...Cl hydrogen bonds. Inter­layer association is accomplished by O-Hethanol...Cl and O-H...Oethanol hydrogen bonds and [pi]-[pi] stacking inter­actions [centroid-centroid distances vary from 3.6477 (12) to 3.8381 (11) Å]. A supra­molecular three-dimensional architecture results from a stacked arrangement of layers comprising the ionic and hydrogen-bonded components.

Comment top

Bifunctional organic ligands have proven very efficient building units in the construction of metal-organic frameworks (MOFs) (MacGillivray, 2010). In particular, one may expect new MOF-architectures from ligands comprising two different coordination sites (Noro et al., 2010). Due to the well known complexation properties of quinolin-8-ol (Albrecht et al., 2008; Weber & Vögtle, 1975) and taking into account the commonly noted coordination behaviour of carboxylic acid groups to various metal ions (Kitagawa et al., 2004; Böhle et al., 2011), corresponding ligands featuring both these structural elements are rated high in this connection. Preparation of a respective hetero bifunctional ligand led to the formation of the title compound. This was isolated as crystals which were found to be a hydrochloride salt containing included ethanol.

In the structure of the title compound (Fig. 1), the principal molecule has an E configuration with reference to the ethenyl bond, C10C11. The overall geometry of this molecule shows approximate planarity with the largest atomic distance from the mean plane of the quinolinium moiety (N1/C1-C9) being -0.018 (1) Å for C8 and 0.011 (2) Å for C9, whereas the phenyl ring (C12-C17 ) is perfectly planar. The dihedral angle between the mean planes of these aromatic building blocks is 3.4 (1) °, while the carboxy substituent (C18/O2/O3) is inclined at an angle of 4.8 (4) ° referring to the phenyl ring. The bond distances within the quinolinium moiety are within expected values (Tan, 2007; Zinczuk et al., 2008).

The chloride ion, Cl1, can be considered as a nodal point within the coordination pattern of the molecules as it is connected with the hydroxy hydrogen [O1—H1···Cl1 2.26 Å, 173 °], the quinolinium hydrogen [N1—H1 A···Cl1 2.38 (2) Å, 151 (2) °] and more weakly (Desiraju & Steiner, 1999) to an ethenyl hydrogen [C10—H10···Cl1 2.69 Å, 138 °] of two different cations. Details are given in Fig. 2 and Table 1. In addition, one molecule of solvent (EtOH) is coordinated by its hydroxy hydrogen to the anion [O1G—H1G···Cl1 2.26 Å, 179 °; see Table 1 and Fig. 2].

In the crystal, there is a layered arrangement of molecules, which apart from the ionic interactions is stabilized by conventional N-H···O and O-H···O hydrogen bonds (Fig. 2 and Table 1). Moreover, in the stacking direction of the molecular layers the mean distance of 3.50 Å between consecutive molecules and the overlap of their aromatic units suggest the presence of ππ interactions (James, 2004). These include Cg1···Cg1i = 3.7477 (12) Å, normal distance = 3.3605 (8) Å, slippage = 1.659 Å; Cg1···Cg2i = 3.8381 (11) Å; Cg1···Cg3ii = 3.6477 (12) Å; Cg2···Cg3ii = 3.7241 (12) Å [Cg1, Cg2 and Cg3 are the centroids of rings C5-C8/N1/C9, C1-C5/C9 and C12-C17, respectively; symmetry codes: (i) -x+1, -y, -z+2; (ii) -x+1, -y+1, -z+2].

Experimental top

The title compound was synthesized via Knoevenagel type condensation (Yuan et al., 2012) using 8-hydroxyquinaldine (320 mg, 2.0 mmol) and 4-formylbenzoic acid (1.20 g, 8.0 mmol) in acetic anhydride (100 ml). The mixture was stirred for 30 h under reflux. After removal of the solvent, the residue was dissolved in 100 ml of pyridine/water (v/v = 4:1) and heated at 373 K for 1 h. Evaporation of the solvent under vacuum and purification of the crude product by recrystallization from ethanol and treatment with hydrochloric acid (37%) yielded 370 mg (63%) of the title compound as brown crystals. The E configuration of the compound was confirmed by 1H NMR analysis (ethenylene protons); M. p. = 514 K.; MS (ESI) m/z: found 292.0 [M+H]+; calc. for C18H18NO3 291.09. Spectroscopic data, including IR and 1H and 13C NMR, for the title compound are available in the archived CIF.

Refinement top

Crystal data, data collection and structure refinement details are summarized in Table 1. The NH hydrogen was located in a difference Fourier map and freely refined. All other H atoms were positioned geometrically and constrained to ride on their respective parent atoms: O—H = 0.82 Å, C—H = 0.93, 0.96 and 0.97 Å for aryl/ethenyl, methylene and methyl H atoms, respectively, with Uiso(H) = 1.5Ueq(C-methyl and O), and = 1.2Ueq(C) for other H atoms.

Experimental. Spectroscopic data for the title compound:

IR (KBr, cm-1) 3354, 2810, 2537, 1673, 1284, 1194, 882, 747, 541. 1H NMR (500 MHz, DMSO-d6) 7.07 (d, 3JHH = 7.3 Hz, 1 H), 7.30 (d, 3JHH = 8.0 Hz, 1 H), 7.36 (t, 3JHH = 7.8 Hz, 1 H), 7.52 (d, 3JHH = 16.2 Hz, 1 H), 7.80–7.68 (m, 3H), 7.98 (d, 3JHH = 8.0 Hz, 2 H), 8.13–8.07 (m, 1H), 8.21 (d, 3JHH = 8.5 Hz, 1 H), 9.39 (br s, 1 H). 13C NMR (126 MHz, DMSO-d6) 110.9, 117.4, 120.9, 126.9, 127.1, 127.7, 129.2, 129.8, 130.1, 130.4, 133.1, 136.4, 140.6, 152.8, 152.9, 167.0.

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