Synthesis, characterization and X-ray crystal structures of thiolate sulfur-bridged dimeric copper(II) complexes of the 2-aminoacetophenone Schiff base of S-methyldithiocarbazate

The copper(II) complexes of Cu(apsme)X (apsme = monodeprotonated form of the 2-aminoacetophenone Schiff base of S-methyldithiocarbazate; X = Cl−, Br−, NCS−) self-assemble in solution yielding thiolate sulfur-bridged dimers in which each copper atom adopts an approximately square-pyramidal geometry.
