摘　　要：本文报告一种新的梯形锡氧簇合物[二氯双(μ-乙氧基)双(μ3-氧)八苯基四锡(Ⅳ)]的合成及晶体结构特征。晶体分析结果表明:标题化合物分子式为C52H50Cl2O4Sn4,属于单斜晶系,P21/n空间群,具有平面中心对称的Sn4O4梯形结构。分子中所有锡原子都为五配位的变形三角双锥构型。分子间靠较弱的C—H…π作用力和范德华作用力相互聚集在一起。The title compound （I）, C52H50C12O4Sn4, was obtained as an unexpectedly product, and its crystal structure was determined by X-ray diffraction. The analysis of crystal structure indicated that the title compound exhibits the planar, centro-symmetric ladder structure with a fused Sn4O4 ring system. It crystallizes in the monoclinic and space group P21/n. All the Sn atoms are five-coordinated, possessing rather distorted trigonal bipyramidal coordination geometry. The molecules are holding together by the weak C-H……π interaction and Vander Waals forces in the packing structure.
