Abstract

The title complex, [Cu(C(7)H(3)NO(4))(C(7)H(6)N(2))(H(2)O)]·0.75H(2)O, consists of discrete monomeric units. The Cu(II) atom is coordinated by two carboxyl-ate O atoms and the N atom from a dipicolinate unit and by an N atom from a benzimidazole ligand. The distorted square-pyramidal geometry is completed by a longer axial bond to the O atom of a water mol-ecule. The mol-ecular structure and packing are stabilized by classical O-H⋯O and N-H⋯O hydrogen bonds, also including a disordered crystal water molecule.
