The title compound, [Cu(C2Cl3O2)2(C3H4N2)4], was prepared by the reaction of imidazole and trichloroacetatocopper(II). The CuII atom adopts a distorted octahedral coordination geometry, binding the N atoms of four imidazole ligands and the carboxylate O atoms of two trichloroacetate anions. The molecular structure and packing are stabilized by N—HO hydrogen-bonding interactions. Close intermolecular ClCl contacts [3.498 (3) Å] are also found in the structure.
