镓络合物稳定性规律及其应用的研究

A STUDY ON THE STABILITY OF GALLI UM COMPOUNDS

利用空间堆积模型，对１４０多种镓络合物的晶体结构数据进行了立体角系数之和的计算，发现存在着一个以０．９５１（ＳＡＳ）为中心、以０．０７５为特征误差的稳定区间，它说明了镓周围配体的堆积程度。利用配体交换反应，对镓络合物进行了研究，实验结果与稳定性规律所预测的结果一致。

The crystal data of more than14 0 gallium com pounds are used to calculate the sum of solid angle factors in the cone packing model. It is found that the solid angle factor sums(SAS)of all coordina-ting ligands reach to a stable region with an average value of 0.95 1 and a characteristic error σ=0.075. The stability of a few gallium compounds can be predicted by SAS , and tested by ligand ex-change reaction. The experimental results are consistent with SAS.
