确定AB_m型分子几何构型的[T/2-3m]规则

The [T/2-3m] rule of estimating geometric configuration of AB_m type molecules

针对VSEPR及 8n + 2m和 6n规则的不足之处 ,提出一个简便、适用范围广的 [T/2 - 3m]规则 .运用该规则时 ,只需要ABm 型分子的总价电子数和非氢配位数 ,就能确定中心原子的轨道杂化形式 。

This paper points out the deficiencies of the rule of "VSEPR and 8n+2m and 6n" , and raises a simple and widely applicable "[ T/2-3m ] rule". When the rule is applied, the total valence electrons and non-hydrogen coordination num ber of AB m -type molecule are only required, we may estimate the hybridize d orbital type and therefore induce the geometric configuration of the molecules .
