Abstract: In the title compound, [Zn(C8H5N2O2)2(H2O)], the ZnII 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)°. The three-dimensional framework is organized by intermolecular N-H...O hydrogen bonding and O-H...O interactions and [pi]-[pi] interactions between adjacent benzimidazole rings [centroid-centroid distance = 3.586 (3) Å].
