| 摘要: 从库仑定律出发,采用最优化法,计算了MLaLb′型配合物各种几何异构体的几何构型稳定化能。在计算中考虑了配体L、L′的相对电荷。 计算结果表明,对称性是决定构型的首要因素。具体构型与配体的相对电荷有关。 在若干配合物中,中心原子的dn构型决定其构型的骨架。 配体对构型的作用也应予考虑。对共价性程度大的配合物,应考虑轨道重叠对构型的影响。 |

| Abstract: According to Coulomb's law,the geometric stabilization energies for different isomers of MLaLb' type coordination compounds (C.N.=4-7) have been calculated by optimum seeking method,In calculation,the relative charge of ligands has been taken into consideration.The results of calculation shuw that symmetry is a prime factor which determines the stereochemistry of compounds. The actual structure is also dependent on the relative charge of ligands.In some cases,the dn configuration of central atom determines the frame of structure. Ligand effects should also be considered. For the coordination compounds having rather strong covalent bond,the orbital overlap should be considered,too. |
