  Dicyclopentadienyl complexes of ytterbium(III). The crystal structure of [Yb(η5-C5H4SiMe3)2(μ-Cl)]2

  摘要：

  The title complex was prepared by reaction of YbCl3 with Li (C(5)H(4)SiMe(3)) in tetrahydrofuran. A single crystal X-ray diffraction study has revealed that the complex is dimeric with bridging chlorine atoms. A flattened tetrahedron around each ytterbium atom is formed by the centroids of two cyclopentadienyl rings and the two bridging chlorine atoms. Comparison of bond distances and angles with those reported for similar dicyclopentadienylytterbium complexes shows that substitution on the cyclopentadienyl ligands by bulky trimethylsilyl groups does not affect the stereochemistry about the lanthanide atom.

  The crystal and molecular structure of (η5 -C5H5)YbCl2(THF)3 (1), which crystallizes e.g. from solutions of [(C5H5)2YbCl]2 in THF, fully corresponds to the structure of the previously examined Er-homologue. In accordance with its rather high SAS-value (0.784), 1 loses spontaneously two THF ligands when exposed to toluene.

  的晶体和分子结构（η 5 -C 5 H ^ 5）YbCl 2（THF）3（1），它从溶液中结晶例如[（C 5 H ^ 5）2 YbCl] 2的THF溶液，充分对应于结构以前检查过的Er-同源物。根据其相当高的SAS值（0.784），当1暴露于甲苯时，它会自发失去两个THF配体。
