以四氢呋喃为溶剂，在回流温度下，由原位生成的双金属“Na_3Sb”和二甲基苯基氯硅烷以中等产率合成了三（二甲基苯基硅基）锑（1）。通过标准分析和光谱技术鉴定产物，并通过单晶X-射线衍射（三斜晶系，空间群P1，Z = 2）确定晶体结构。SbSi 3骨架为金字塔形（平均Si-Sb-Si角为100.2°，平均Sb-Si键长为2.558 A），Me 2 PhSi基团呈交错构象。
Tris(dimethylphenylsilyl)antimony (1) was prepared in moderate yield from dimetallic “Na3Sb” (generated in situ) and chlorodimethylphenylsilane in tetrahydrofuran at reflux temperature. The product was identified by standard analytical and spectroscopic techniques, and the crystal structure was determined by single-crystal X-ray diffraction (triclinic, space group P1, Z = 2). The SbSi3 skeleton is pyramidal (average Si-Sb-Si angle 100.2°, average Sb-Si bond length 2.558 A), and the Me2PhSi groups are in a staggered conformation.
