摘要: d9电子构型的金属离子所形成的配合物几何构型一般为拉长八面体或平面正方形,晶体场理论和角重叠模型都对此作出了较满意的描述[1,2],但就该电子构型的中心离子与指定配体配位时易形成配合物的配位数、配体所处的位置等问题,至今尚无满意解释.本文通过分子轨道稳定化能(MOSE)的计算及其曲面的绘制,形象地解释了上述问题.

关键词: 分子轨道稳定化能, 几何构型, 姜-泰勒效应

Abstract: The molecular orbital stabilization energy resulting from the coordination of ligands was calculated for the d9 coordination compounds, in which the ligands are coordinated from different space directions into the centre ion with different distributions of electrons.The molecular orbital stabilization energy curved surface has been drawn.Consequently, the geometric configuration of d9 coordination compound has been satisfactorily accounted for.

Key words: Molecular orbital stabilization energy, Geometric configuration, Jahn-Teller effect
