二十面体金属碳硼络合物L2MCnB11-n(L=R3P,RNc;M=Pd,Pt;n=1,2)的晶体结构分析表明,滑移变形的大小和方向取决于配体开放五角面上的取代基,扩展的Huckel计算解释了观察到的几何构型。
Crystal structure analyses of the icosahedral metallacarborane complexes, skeletal L2MCnB11–n(L = R3P, RNC; M = Pd, Pt; n= 1,2), have shown that the magnitude and direction of the slipped distortion depends on the substituents on the open pentagonal face of the ligand; extended Huckel calculations on model borane complexes have accounted for the observed geometries.
