A series of complexes were synthesized using piazselenole(NS) 5-methyl piazselenole(MB) and 4,5-benzopiazselenole(BS)as ligands and Cu2+ as cation in liquid-phase and solid-phase reaction.The complexes were characterized and compared by ICP-AES,EA,IR,UV-Vis,and XRD etc.The coordinating mechanism and the spectral properties are also discussed.
