Aqua-bis(1H-benzimidazole-2-carboxyl-ato-κO,N)zinc(II).

In the title compound, [Zn(C(8)H(5)N(2)O(2))(2)(H(2)O)], the Zn(II) ion is coordinated in each case by a carboxyl-ate O atom and an imidazole N atom from two different benzimidazole-2-carboxyl-ate (BIC) ligands and one water O atom in a trigonal-bipyramidal geometry. In the complex mol-ecule, the two benzimidazole planes are twisted, making a dihedral angle of 55.93 (11)°. The three-dimensional framework is organized by inter-molecular N-H⋯O hydrogen bonding and O-H⋯O inter-actions and π-π inter-actions between adjacent benzimidazole rings [centroid-centroid distance = 3.586 (3) Å].
