摘　　要：Six new ethylthioethylcyclopentadienyl-containing organolanthanide complexes CpTh 2LnCl [Ln=Gd (1), Dy (2)] and Cp2LnCpTh [Cp=C5H5, Ln=Yb (3), Sm (4), Dy (5), Y (6)] were synthesized by the reaction of ethylthioethyl-cyclopentadienyl (CpTh) sodium salt with LnCl3 or Cp2LnCl in THF. Complexes 16 were characterized by ele-mental analyses, infrared and mass spectroscopies. The molecular structures of complexes 13 were also deter-mined by the X-ray single crystal diffraction. The results show that the side-chain sulfur atom on the ethylthio-ethylcyclopentadienyl ring can form intramolecular chelating coordination to the central lanthanide ion, improving the stability of organolanthanide complexes and reducing the number of coordinated THF molecules.Six new ethylthioethylcyclopentadienyl-containing organolanthanide complexes CpTh 2LnCl [Ln=Gd (1), Dy (2)] and Cp2LnCpTh [Cp=C5H5, Ln=Yb (3), Sm (4), Dy (5), Y (6)] were synthesized by the reaction of ethylthioethyl-cyclopentadienyl (CpTh) sodium salt with LnCl3 or Cp2LnCl in THF.
