Synthesis, Characterization and Thermal Decomposition of Ln (Me2dtc)3(phen)

摘要：

Four solid complexes of Ln (Me<,2>dtc)<,3>(phen) (Ln=Eu, Gd, Tb, Dy) were synthesized in anhydrous ethanol by the reaction of lanthanide chloride low hydrate with the mixed ligands of sodium dimethyldithiocarbamate and 1, 10-phenanthroline·H<,2> O (abbreviated as phen·H<,2>O), and characterized by elemental analysis, IR spectroscopy, TG-DTG and X-ray diffraction techniques. Combining with the crystal structures, the complexes are identified as the general formula of Ln (Me<,2>dtc)<,3>(phen). TG-DTG with X- ray powder diffraction showed that these compounds could decompose to lanthanide sulfides under relatively lower temperature, which indicated that the title complexes could be ideal precursors to prepare lanthanide sulfides.
