Aquabis(1H-benzimidazole-2-carboxylato-κ2O,N3)zinc(II)

In the title compound, [Zn(C8H5N2O2)(2)(H2O)], the Zn-II ion is coordinated in each case by a carboxylate O atom and an imidazole N atom from two different benzimidazole-2-carboxylate (BIC) ligands and one water O atom in a trigonal-bipyramidal geometry. In the complex molecule, the two benzimidazole planes are twisted, making a dihedral angle of 55.93 (11)degrees. The three-dimensional framework is organized by intermolecular N-H center dot center dot center dot O hydrogen bonding and OH center dot center dot center dot O interactions and pi-pi interactions between adjacent benzimidazole rings [centroid-centroid distance = 3.586 (3) angstrom].
