were obtained from water, alcohol or acetonitrile solutions. The copper(II) complexes have been prepared in high yields using metallic copper powder. The compounds were characterized by IR, UV/VIS spectroscopy, magnetochemistry and X-ray analysis. The crystal and molecular structures of [CuL2(H2O)] and [CuL2(4-mpy)2](4-mpy = 4-methylpyridine) have been determined. In both complexes the anions adopt a cis-anti
