bipyramidal. The structure of the complex forms an unusual polymeric zig-zag planar network. The FT-IR and the 119Sn Mossbauer studies supported the formation of trigonal bipyramidal (Tbp) molecular structures, both in the diorganotin(IV) and triorganotin(IV) derivatives, even if, in the case of diorganotin(IV) derivatives, the tetrahedral structure cannot be a priori excluded.

摘要磷酸霉素二钠盐抗生素[(1R,2S)-1,2-环氧丙基膦酸酯]的四个新的二有机锡(IV)(R = Me,Bu)和三有机锡(IV)(R = Me,Ph)已合成了Na2,并通过X射线晶体学,FT-IR,Mossbauer,UV-Vis光谱学研究了它们的固态构型。对双[三甲基锡(IV)]磷霉素进行的X射线衍射研究表明,所有Sn原子的配位几何均为三角双锥体。配合物的结构形成不寻常的聚合物之字形平面网络。FT-IR和119Sn Mossbauer研究支持在二有机锡(IV)和三有机锡(IV)衍生物中形成三角双锥体(Tbp)分子结构,即使在二有机锡(IV)衍生物的情况下为四面体结构不能先验地排除。
