文摘

Six new organolanthanide complexes, Cp₂Ln(C₁₀H₇COCHCOCF₃) [Ln = Dy (1), Tb (2), Gd (3), Eu (4), Tm (5)] and Cp₂Yb(C₁₀H₇COCHCOCF₃)(THF) (6) (Cp = cyclopentadienyl, THF = tetrahydrofuran), have been synthesized. All these complexes are identified by elemental analysis and IR. The crystal structure of Cp₂Yb (C₁₀H₇COCHCOCF₃)(THF) has been determined by single-crystal X-ray diffraction. The central ytterbium atom is surrounded by two η⁵-cyclopentadienyl ligands, two oxygen atoms of the 2-naphthoyltrifluoroacetonato ligand and one oxygen atom of the solvated THF molecule.
