N2 - Unactivated copper metal powder and zinc oxide readily react with ethylenediamine (en) in nonaqueous [methanol, dimethylformamide (dmf), dimethyl sulfoxide (dmso), acetonitrile] solutions of ammonium salts under ambient conditions producing, in high yields, a series of heterobimetallic complexes of general formula [Cu(en)2ZnX4]•(Solv), where X = Cl, Br, NCS, CH3COO (OAc); Solv = dmf, dmso, CH3CN, H2O. The single-crystal X-ray analysis of the complexes reveals chain structures, which are based on the completion of the octahedral coordination of CuII by two bridging X atoms from ZnX42−. The ZnX42− is shown to be a distorted tetrahedron (Cl, Br, NCS) or a very distorted octahedron (OAc) and to behave as a one- or two-linking centre bridging ligand. The chains are found to be zigzag [Cu(en)2ZnCl4]•dmso (1), [Cu(en)2ZnCl4]•dmf (2), [Cu(en)2Zn(NCS)4]•CH3CN (3), quasi linear [Cu(en)2Zn(OAc)4] (4), or helical, [Cu(en)2Zn(NCS)4]• 0.5H2O (5), depending on the nature of the anion and solvent. Complex 4 represents the first compound containing Zn(OAc)42− to be crystallographically authenticated.
