Synthesis,Crystal Structure and Electrochemical Properties of the One-Dimensional Chain Tri(n-butyl)tin 2,4-Dichloro-phenoxy Acetate

有机锡化合物因具有抗癌活性和杀菌、杀螨作用,以及结构特点多变、反应性丰富,近年来引起了人们的高度关注,已合成出许多结构新颖和性能特殊的有机锡化合物。研究发现,有机锡化合物中,中心锡原子的配位形式取决于与锡原子直接相连的烃基结构及配体的类型。改用不同的烃基和配体，锡原子可以形成四配位、五配位、

A one-dimensional chain tri（n-butyl）tin 2,4-dichloro-phenoxy acetate has been synthesized and charact-erized by IR,1H NMR spectra and elemental analysis.The crystal structure has been determined by X-ray diffraction. The crystal belongs to monoclinic space group P21/c with a=1.350 1（8） nm,b=1.785 4（3） nm,c=1.049 2（2） nm,β=105.146（10）°,Z=4,V=2.441 4（2） nm3,Dc=1.388 Mg·m-3,μ（Mo Kα）=1.280 mm-1,F（000）=1 040,R1=0.044 2,wR2 =0.121 9. In the complex,tin atoms are five-coordinated distorted trigonal bipyramid configuration with bridging 2,4-dichloro-phenoxyacetic acid carboxy. The result of analysis shows that the electron transfer in electrode reaction is irreversible. CCDC：715238.
