2,5-二巯基-1,3,4-噻二唑稀土有机配合物的合成及表征

Synthesis and Characterization of MixedLigand Rare Earth OrganometallicComplexes Involving Both Cyclopentadienyl (or Methylcyclopentadienyl) and2,5dimercapto1,3,4thiadiazole Chelate Ligands

用２，５－二巯基－１，３，４－噻二唑与三环戊二烯基或三（甲基环戊二烯基）稀土配合物反应，合成了五个分子内含Ｌｎ－Ｓ与Ｌｎ－Ｎ配键的稀土金属有机配合物。这些配合物均经过元素分析、红外光谱及质谱表征。有关数据表明，它们都是二齿配位的双核配合物。

Five new mixedligand rare earth organometallic complexes of the general formula R4Ln2L(R=5C5H5 or 5C5H4CH3,Ln=Y,La,Tb,Ho,Yb,L=2,5dimercapto1,3,4thiadiazole) have been synthesized.All the complexes were characterized by elemental analysis,IR and MS.Results show that the ligand coordinates to the central metal with S and N atoms in bidentate fashion.
