摘要：

In this work the synthesis and characterization of a novel class of organolanthanide compounds: [Ln(C5H4CH=CH2)(2)Cl], Ln=La, Sm, Eu, Gd, Dy, Er; [Ln(C5H4CH=CH2)Cl-2], Ln=Nd, Tb and [Dy(C5H4CH=CH2)(3)] are presented. Compounds were characterized by elemental analyses, complexometric titration with EDTA, argentimetric titration, thermal analyses, magnetic susceptibility and vibrational spectra in the infrared region. According to the infrared spectra, a sigma-centered bonding is assumed, corresponding to a local symmetry C-5v, for the vinylcyclopentadienyl anion. (C) 2000 Elsevier Science S.A.
