摘　　要：本文通过2,3,4,5-四氟苯甲酸与二丁基氧化锡按照1:1的摩尔比,在苯中回流4个小时,得到了一种新型的四核含氟有机锡羧酸配合物{[(2,3,4,5-F4C6HCO2)Bu2Sn]2O}2,通过元素分析、红外光谱和核磁氢谱以及X-射线单晶衍射仪进行了结构表征,结果显示,在该配合物中,四个锡原子通过两个μ3-氧桥连接,四周通过四个羧基配体以单齿和螯合两种配位方式与锡原子配位,形成了一个梯形的Sn-O-Sn构架,且每个Sn原子周围都是五配位三角双锥几何构型.A novel fluorine - containing four nuclears organotin carboxylate complex： { [ （ 2,3,4,5 - F4CrHCO2 ） Bu2Sn] 2O } was obtained by 2,3,4,5 - tetrafluoro - benzoic acid and di - n - butyltin oxide in a molar ratio of 1 ： 1 refluxing for 4 laours in benzene. This complex was characterized by elemental analysis, IR and ^1H NMR and X - ray single crystal diffraction structural analysis. The results shows that four tin atoms was connected through an two μ3 - oxygen bridge and surrounded by four carboxyl ligand with two kinds of coordi- nated modes： monodentate and chelating, forming a trapezoidal Sn -O -Sn architecture and each Sn atom is surrounded by five -coordinate trigonal bipyramidal geometry.
