In the crystal structure of the title mol­ecular adduct, C9H7N·C8H12O4, the two species are ­linked through a carb­oxy­lic acid–isoquinoline O—H⋯N hydrogen bond. These mol­ecular pairs then inter-associate through the second acid group of the cis-cyclo­hexane-1,2-dicarb­oxy­lic acid molecules, forming a classic centrosymmetric cyclic head-to-head carb­oxy­lic acid–carboxyl O—H⋯O hydrogen-bonding association [graph-set R22(8)], giving a zero-dimensional (cluster) structure, consisting of two of each species.

Comment top

Although the structure of racemic cis-cyclohexane-1,2-dicarboxylic acid is known (Benedetti et al., 1970), together with its 1:1 adduct with 4,4'-bipyridine (Bhogala et al., 2005), there are few examples of salts of this cis-acid in the crystallographic literature. We have previously reported the structures of the anhydrous 1:1 ammonium salt (Smith & Wermuth, 2011a) and the 2-aminopyridinium salt (Smith & Wermuth, 2011b). Our 1:1 stoichiometric interaction of cyclohexane-1,2-dicarboxylic anhydride with isoquinoline in 50% ethanol–water solution gave minor crystals of the 1:1 adduct C8H12O4. C9H7N, formed in a residual oil, and the structure is reported here.

In the structure of the title adduct (Fig. 1), the two molecular species are interlinked through a carboxylic acid O—H···Nisoquinoline hydrogen bond (Table 1). The molecule pairs then associate through the second acid group, forming a classic centrosymmetric cyclic head-to-head carboxylic acid–carboxyl O—H···O hydrogen-bonding interaction (Leiserowitz, 1976) [graph set R22(8) (Etter et al., 1990)] giving a zero-dimensional structure (Fig. 2).

For the structures of the racemic 1:1 ammonium and 2-aminopyridinium salts of this acid, see: Smith & Wermuth (2011a,b). For the structure of the 1:1 adduct with 4,4'-bipyridine, see: Bhogala et al. (2005). For hydrogen bonding in carboxylic acids and graph-set analysis, see: Leiserowitz (1976); Etter et al. (1990).

Experimental top

The title compound was synthesized by heating a solution of 1 mmol of cyclohexane-1,2-dicarboxylic anhydride and 1 mmol of isoquinoline in 50 ml of 1:1 ethanol–water under reflux for 10 min. After concentration to 30 ml the solution was allowed to evaporate at room temperature, giving a viscous oil which eventually gave minor colourless crystals (m.p. 439–441 K) from which a specimen was cleaved for the X-ray analysis.

Refinement top

The carboxylic acid H atoms were located by difference methods and their positional and isotropic displacement parameters were refined. Other H-atoms were included in the refinement at calculated positions [C—H = 0.93–0.98 Å and with Uiso(H) = 1.2Ueq(aromatic C), or 1.5Ueq(aliphatic C), using a riding-model approximation.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
