Four solid complexes of Ln(Me2dtc)3(phen) (Ln=La, Pr, Nd, Sm) were synthesized in anhydrous ethanol by the reaction of lanthanide chloride low hydrate with the mixed ligand of sodium dimethyldithiocarbamate and 1, 10-...Four solid complexes of Ln(Me2dtc)3(phen) (Ln=La, Pr, Nd, Sm) were synthesized in anhydrous ethanol by the reaction of lanthanide chloride low hydrate with the mixed ligand of sodium dimethyldithiocarbamate and 1, 10-phenanthroline·H2O (phen·H2O), and characterized by elemental analysis, IR spectroscopy, TG-DTG, and X-ray diffraction analysis. TG-DTG with X-ray powder diffraction showed that these compounds could decompose to lanthanide sulfides at relatively lower temperature, which indicated that the title complexes could be favorable precursors to prepare lanthanide sulfides.展开更多
Four solid complexes of Ln(Me2dtc)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...Four solid complexes of Ln(Me2dtc)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·H2O (abbreviated as phen·H2O), 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(Me2dtc)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.展开更多
