研究了(CH_3C_5H_4)_3Ln·THF (Ln = Sm,Ho,Tb,Yb)与环戊二烯高产率生成 (C_5H_5)_3Ln·THF的新反应。反应产物经过了元素分析、质谱和X射线的表征。产 物(C_5H_5)_3Ln·THF的特征结构参数，如五元碳环的碳原子与中心金属的平均距 离，五元碳环质心与中心金属距离，配位的四氢呋喃氧原子与中心金属距离，由于 “镧系收缩现象”，随着中心原子序数的增加而减小。

A novel reaction of(CH_3C_5H_4)_3Ln·THF (Ln = Sm,Ho,Tb,Yb)with cyclopentadiene obtained (C_5H_5)_3Ln·THF in high yield. The products were characterized by elemental analyses, MS and X-ray diffraction analysis. The data of selected structure parameters of (C_5H_5)_3Ln· THF, such as the average distance between the penta carbon ring and the central metal, the distance between the penta carbon center or the coordinated THF and the central metal, showed that their values decreased with the increase of atomic number. It suggests that these compounds obey the "lanthanide contract" rule.
