摘 要:采用1,6-二氯十二甲基六硅烷与对溴苯甲醚的格氏试剂反应制得了标题化合物。对其进行了结构分析。X射线衍射分析表明,该晶体属单斜晶系,分子是中心对称的,化合物呈交叉锯齿型稳定构象。The title compound was synthesized by the reaction of 1,6-dichlorodode camethyl hexasilane with the Grignard reagent of p-bromoanisole.The physical properties of this compound were reported and its structure was determined by four cycle diffractometer.The crystal is monoclinic system,space group P21/C,the parameters of crystal cell are:α=8.856(2)A,b=11.886(2)A,C=16.823(3)A;β=99.04(1)°;V=1749A^(3),Z=2,D_(c)=1.077g·cm^(-3).The final R factor is 0.041.The structure analysis showed that the molecule is central symmetric.The stable conformation is staggered.The planes of benzene ring and Si(l)-Si(2)-Si(3)are almost perpendicular each other.In this case the σ_(Si-Si)-π interaction of benzene ring and σ_(Si(1)-Si(2)) bond is more favourable.
