| Abstract: The title complexes M(mnt)(bpy), M = Ni(Ⅱ), Cu(Ⅱ), Zn(Ⅱ),are synthesized by reaction of Na2(mnt) with relevant M(bpy)Cl2, respectively. The elemental analysis, IR, DTA-TG, and molar conductivitics showed these complexes as having electroneutrality with approximate square planar structures. The M-S bond is slightly stronger than the M-N bond. They are themostuble colour solid under temperature 310℃. The electronic spectra of the complexes in various solvate exhibited intensive absorption bands at 240-290nm (π-π* in bpy and mnt),340-400nm (π-π* in mnt). And intensive absorption band at 420-500nm is assigned as a metal-dithiolene π to bpy π* change-transfer transition. The absorptions for Ni(mnt)(bpy) at 650-880nm are observed also in lgε 2.0-3.0. At room temperature, under the excition of ultra violet light the complexes all exhibit an intensive fluorscent emission at 520nm (in solid state) or at 600-800nm (in solution). |
