【摘要】 本文合成了一些[M（THF）₂][L₂LnCl₂]络合物,其中Ln为Nd,Gd或Yb;L为C₅Me₅,C₅Me₄C₂H₅或C₅Me₄C₃H₇;M为Li或K。并分离了中性络合物（C₅Me₄C₃H₇）₂NdCl。这些络合物对空气和水非常敏感,除了含K的阴离子型络合物外,其它络合物都易溶于汽油,苯和甲苯等非极性溶剂。络合物均经元素分析、红外和核磁鉴定。更多还原

【Abstract】 Anionic complexes[M（THE）₂][L₂LnCl₂],where M is Li or K,Ln isneodymium,gadolinium or ytterbium,L is C₅Me₅,C₅Me₄C₂H₅ or C₅Me₄C₃H₇,have beensynthesized from LnCl₃ and substituted cyclopentadienyl M.The neutrál complex[C₅Me₄-C₃H₇]₂ NdCl has also been isolated.With the exception of[K（THF）₂][（C₅Me₄C₃H₇）₂-LnCl₂],these complexes are extremely sensitive to air and moisture.All of the complexesare soluble in aprotic solvents such as petrol,benzene and toluene:The complexes were identified by elemental analysis,IR and（?）H NMR.更多还原
