双三烃基锡1,1′-二茂铁二甲酸盐的合成及晶体结构

Synthesis and X-ray Diffraction Crystal Structure ofBis(trialkyltin) 1, 1'-ferrocene Dicarboxylates

合成了１３个新的双三烃基锡１,１'－二茂铁二甲酸衍生物,并进行了化合物的波谱表征．Ｃｙ２ＭｅｓｎＯＯＣＦｃＣＯＯＳｎＭｅＣｙ２的Ｘ射线衍射单晶结构测定表明,其结构为单斜晶系,Ｆｄｄ２空间群,晶胞参数:α＝１．８７３ ５(４)ｎｍ,ｂ＝３．５９３ ０(７)ｎｍ,ｃ＝１．１１２ ２(２)ｎｍ;α＝β＝γ＝９０．００(０)°;Ｖ７．４８７(４)ｎｍ３;Ｚ＝８;Ｆ(０００)＝３ ５５２;最终可靠因子Ｒｔ＝０．０４８,Ｒｗ＝０．０５４．为五配位轻微畸变的三角双锥的线性聚合结构化合物．

Thirteen new bis(trialkyl)tin 1, 1' -ferrocene dicarboxylates were synthesised and characterizedby IR, 1H NMR, MS and elemental analysis. The X-ray diffraction crystal structure ofMeCy2SnO2CC5H4FeC5H4CO2SnCy2Me was determined. The results show that the Sn atom is in slighlydistorted trigonal-bipyrimidal environment. The compound has a linear polymer's structure.
