摘要
根据ＭＡＤ－ＳＣＣ－ＥＨＭＯ法的计算结果，用衡量相对稳定性的三个指标：稳定化能、ＨＯＭＯ－ＬＵＭＯ能隙和重迭集居比较了无机环Ｓ２Ｎ２与有机环的夹心和半夹心配合物的相对稳定性，并用碎片分子轨道法讨论了Ｓ２Ｎ２环分子轨道与过渡金属ｄ轨道间的相互作用以及配合物的成键情况和电子结构．
Based on the MAD-SCC-EHMO calculated results, the relative stabilities of sandwich and chelate complexes of inorganic ring S 2N 2 and organic ring are compared by using stability indeces: stabilization energy, HOMO-LUMO gap and overlap population. Fragment Molecular Orbital approach is used for discussing the interactions between molecular orbitals of S 2N 2 ring and d orbitals of transition metal, and the electronic structures and bondings in these complexes are also discussed.
