摘要
对近百种铟化合物结构中配体的立体角系数之和进行了计算。发现存在一个以0.797为中心,以б=0.063为特征误差的稳定区间。它反映了铟周围配体堆积的限度。利用堆积参数计算了InAB_4和InAB_3型配合物的键角与实验值一致。说明堆积参数可以在设计未知In配合物方面的应用。
By study of structures of near 100 In-compounds based on the recently developed cone packing modle. It is found that the solid angle factors sum (SAS) of all coordinating ligands reach to a stable region with an average value 0.797 and a characteristic errorб=0.063. It reflects the limits of the packing of ligand around In ions. The bond angles in the compounds of the coordination pattern like InAB_4 and InAB_3 are calculated in good agreement with experimental values. The applications of the quantitative calculation of the steric effects in the prediction and design of In-compounds are also dis- cussed.
