Preparation, properties and structural characterization of 2-oxathioamidate complexes
摘要:
The reactions of potassium 2-thiooxamate (K+HL-) and potassium N-methyl-2-thiooxamate (K+HA-) with divalent metal ions yield a variety of products. The anions HL- and HA- behave as O,S bidentate chelating ligands, while L2- and A2- act as O,N/O,S bis-bidentate bridging ligands yielding polymeric complexes. The crystal structures of trans-[Mn(HL)2(H2O)2], trans-[Cd(HL)2(H2O)2] and cis-[Mn(HA)2(H2)2].H2O have been solved. Some properties of the complexes prepared are also described.
