Abstract

In the title mononuclear complex, [Cu(C(8)H(7)O(2))(2)(C(7)H(6)N(2))(2)], the Cu(II) atom lies on an inversion centre and is coordinated by two O atoms of two monodentate 4-methyl-benzoate ligands and two N atoms of two benzimidazole ligands in a square-planar geometry. The mol-ecules are linked into chains running parallel to the b axis by inter-molecular N-H⋯O hydrogen bonds and by π-π stacking inter-actions [centroid-centroid distance = 3.669 (2) Å] involving centrosymmetrically related imidazole rings.
