在严格的无水无氧条件下无水ＮｄＣｌ３和ＳｍＣｌ３与Ｎａ２（Ｃ５Ｈ４ＳｉＭｅ２）２Ｏ以１∶１摩尔比在四氢呋喃溶液中反应，得标题配合物［Ｏ（Ｍｅ２ＳｉＣ５Ｈ４）２Ｌｎ（μ－Ｃｌ）（ＴＨＦ）］２［Ｌｎ＝Ｎｄ（１），Ｓｍ（２）］．元素分析证明配合物１和２的组成．Ｘ射线衍射分析证明１和２是通过氯原子桥联的二聚体结构．
The title compound [O (Me2SiC5H4) 2Ln (μ-Cl) (THF)) was obtained by the reaction of anhydrous NdCl3 and SmCl3 with Na2 (C5H4SiMe2) 2O in a 1: 1 molar ratio in tetrahydrofuran solution under the strict anhydrous anaerobic conditions. ] 2 [Ln = Nd (1), Sm (2)]. Elemental analysis confirmed the composition of complexes 1 and 2. X-ray diffraction analysis proves that 1 and 2 are dimer structures bridged by chlorine atoms.
