摘　　要：建立了一种新的三棱柱配位结构伸缩变形和扭曲变形的计算方法。计算结果表明，在给定键长条件下，双齿配体齿间距计算值与实测值吻合，且齿间刚性有利于三棱柱配位结构的稳定。在已有三棱柱配位结构化合物基础上进一步总结了配体和中心原子的结构特征。A new calculating method has been proposed for the elongation and twist of trigonal prism.The calculations show that the calculated and determined values of the bite for bidentate trigonal prism complexes are similar and that rigidity of the bite favors the stabilization of the trigonal prism configuration.The structural characteristics of the bidentate ligands and central atoms are further discussed based on the structural data of trigonal prism compounds.The discussion provides a guide for the preparation of new trigonal prism labelled compounds.
