trans-Bis(hydrogen maleato-κO)bis(pyridine-2-carboxamide-κ2 N 1,O)copper(II)

Abstract

In the title compound, [Cu(C4H3O4)2(C6H6N2O)2], the CuII atom lies on a centre of symmetry and adopts a 4+2 elongated octahedral geometry with two hydrogen maleate ligands in axial positions. The complex molecules are linked via N—H...O hydrogen bonds into a two-dimensional network and further form a three-dimensional structure via weak C—H...O interactions.
