摘　　要：通过１［（Ｚ）２（三苯基锡基）乙烯基］环戊醇与Ｂｒ２反应制得了新化合物１［（Ｚ）２（苯基二溴化锡基）乙烯基］环戊醇．通过元素分析、锡含量测定、ＩＲ、１ＨＮＭＲ对其进行了表征并用Ｘ射线衍射法测得了所合成化合物的晶体结构．该化合物属正交晶系，Ｐ２１２１２１空间群，晶胞参数：ａ＝０８６７５（４）ｎｍ，ｂ＝１２５２３（７）ｎｍ，ｃ＝１４００９（８）ｎｍ；Ｚ＝４，Ｖ＝１５２１９ｎｍ３，Ｄｃ＝２．３９ｃｍ３，ｕ＝２３．７２ｃｍ－１．结构分析表明，标题化合物分子为畸变的三角双锥构架，双键的两个氢取顺式结构，分子中Ｏ与Ｓｎ配位。The compound 1 [ (Z) 2(phenyl dibromostannyl) vinyl] cyclopentanol was synthezised by its reaction with Br 2. and the title compound has been characterized by elemental analysis, IR and 1H NMR data. The structure of title compound has been determined by X ray diffraction analysis. Systematic absences showed the space group to be P 2 12 12 1, the cell parametors as followng: a =0.865 7(4) nm, b =1.252 3(7) nm, c =1.400 9(8) nm; Z =4, V =1.521 9 nm 3, D c=2.39 cm 3, μ =23.72 cm -1 . The results suggest that the title compound has a distorted trigonal bipyramidel geogmetry. There is a Z configuration at the double bond and the presence of an intramolecular coordination from O to Sn giving rise to a five membered ring.
