Abstract: In the title compound, [Cu(C₄H₂BrO₄)₂(C₆H₆N₄)₂], the central Cu^II 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-HO, N-HO and C-HO hydrogen bonds lead to a three-dimensional network.
