摘要
本文报导环戊烷基(或烯丙基)环戊二烯基稀土二氯化物的合成。用元素分析,热分析、红外光谱、质谱和核磁共振谱表征了这两类化合物组成为C_5H_9C_5H_4LnCl_2·nTHF和C_3H_5C_5H_4LnCl_2·nTHF(Ln=Nd,Sm,Gd;n=0,1,2,3)测定了反应中间体C_5H_9C_5H_4Na·THF的晶体结构。
In this paper the syntheses of cyclopentanyl (ora llyl) cyclopentadienyl lanthanoid dichlo-ride tetrahydrofuranate complexes are first reported. The complexes of C_5H_9C_5H_4·LnCl_2-nTHF and C_3H_5C_5H_4LnCl_2·nTHF (C_3H_9C_5H_4= cyclopentanyl cyclopentadienyl; C_3H_5C_5H_4=allylcyclopentadienyl; Ln = Nd, Sm, Gd; n = 0, 1, 2, 3) are identified by elemental ana-lysis, thermal analysis, IR, MS and NMR measurements. The crysal structure of thereaction intermediate C_5H_9C_5H_4Na·THF was determined by the x-ray diffraction method.
