In the title compound, [Cd(C8H7O2)2(C3H4N2)2(H2O)], the CdII atom is coordinated by four carboxyl­ate O atoms from two bidentate chelating 4-methyl­benzoate ligands, two N atoms from two imidazole ligands and one water mol­ecule in a distorted penta­gonal bipyramidal geometry. Inter­molecular O—H⋯O hydrogen bonds between the coordinated water mol­ecule and the carboxyl­ate O atoms of 4-methyl­benzoate lead to an infinite chain. These chains are further self-assembled into a two-dimensional layer through N—H⋯O hydrogen bonds between the imidazole ligands and carboxyl­ate groups. One of the imidazole ligands is disordered over two positions with site-occupancy factors of 0.737 (4) and 0.263 (4).

Comment top

In the structural investigation of 4-methylbenzoate complexes, it has been found that the 4-methylbenzoate functions as bidentate and monodentate ligands (Song et al., 2007). In this paper, we report the crystal structure of the title compound, a new Cd complex obtained by the reaction of 4-methylbenzoic acid, imidazole and cadmium chloride in alkaline aqueous solution.

As illustrated in Fig. 1, the CdII atom exists in a distorted pentagonal bipyramidal geometry, defined by four carboxylate O atoms from two bidentate chelating 4-methylbenzoate ligands, two N atoms from two imidazole ligands and one water molecule (Table 1). One of the imidazole ligands is disordered over two positions with site occupancy factors of 0.737 (4) and 0.263 (4). Intermolecular O—H···O hydrogen bonds (Table 2) lead to infinite chains, involving the coordinated water molecules as donors and the O atoms of 4-methylbenzoate ligands as acceptors. These chains are further self-assembled into a two-dimensional supramolecular network through intermolecular N—H···O hydrogen bonds between the imidazole ligands and carboxylate groups (Fig. 2).

Experimental top

A mixture of cadmium chloride (0.183 g, 1 mmol), 4-methylbenzoic acid (0.136 g, 1 mmol), imidazole (0.068 g, 1 mmol), NaOH (0.06 g, 1.5 mmol) and H2O (12 ml) was sealed in a 23 ml Teflon-lined reactor, which was heated at 433 K for 3 d and then cooled to room temperature at a rate of 10 K h-1. The crystals obtained were washed with water and dried in air.

Refinement top

H atoms attached to C and N atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 (aromatic) and 0.96 (methyl) Å and N—H = 0.86 Å and with Uiso(H) = 1.2Ueq(C,N). H atoms of the water molecule were located in a difference Fourier map and refined with restraints of O—H = 0.82 (1) Å and H···H= 1.34 (2) Å and with Uiso(H) = 1.5Ueq(O). Site occupancy factors of the disordered imidazole ligand were refined.
