本文利用INDO和E_R定域化方法,对Ⅴ~2(μ-η^2-S~2)~2(SCCH~2)~4和[V~2O~2Cl~6]^2-双核配合物进行了量子化学计算研究,讨论了它们的电子结构和化学键性质,并讨论了利用mulliken键序判别金属原子间成键的可靠.进而基于过渡金属原子主要是以d亚层轨道参与成键,建议用金属原子d亚层的键序讨论键强度的新方法.

The electronic structure and chem. bonding were studied of dimer ligands V2(m-h2-S2)2(S2CCH3)4 and [V2O2Cl6]2- by means of INDO-SCF Edmiston-Ruedenberg (E-R) localized-MO methods. A new method is proposed to determine the bonding properties using populations of d-subshell orbitals.
