Bis(2,2′-biimidazole-κ2N,N′)bis(2-bromofumarato-κO)copper(II)

Abstract

In the title compound, [Cu(C4H2BrO4)2(C6H6N4)2], the central CuII atom lies on an inversion center and is six-coordinated in an octahedral geometry by four N atoms from two chelating biimidazole molecules in the equatorial plane and two O atoms from two 2-bromofumarate ligands in the axial positions. O—H...O, N—H...O and C—H...O hydrogen bonds lead to a three-dimensional network.
