arrangement. This results in a five-coordinated trigonal-bipyramidal geometry around the tin atom with two apical oxygen atoms and three equatorial butyl groups. Mössbauer and CP-MAS 117Sn NMR data for triphenyl- and tri-n-butyltin pentafluorobenzoates, -phenylacetates and cinnamates, taking the X-ray structure of F5C6CHCHCOOSnBu3 as a reference, converge to similar polymeric five-coordinated structures
F 5 C 6= CH = CH = COOSnBu 3的晶体结构分析表明该化合物是聚合的,因为存在以反式-R 3 SnO 2排列桥接两个锡原子的二齿羧酸盐配体。这导致锡原子周围具有五个配位的三角-双锥体几何结构,并带有两个顶部氧原子和三个赤道丁基。穆斯堡尔和CP-MAS 117个为三苯基和三-正丁基锡的Sn pentafluorobenzoates NMR数据,-phenylacetates和肉桂酸酯,以F的X射线结构5 Ç 6 CHCHCOOSnBu 3作为参考,在固态下会聚到类似的聚合物五配位结构。相反,氯仿溶液中的13 C和119 Sn NMR数据明确表明所有化合物在锡处的四面体四配位。未能芳香13 c。化学位移增量和复杂的多重峰模式2D的必要记录19 F 13在订单C HMQC谱完全表征溶液中的新化合物。
