| 摘 要： | 配位键并非典型价键 ,所以在模拟金属配合物时若模拟方法和参数选取不当 ,将会导致不能成键或构型发散。本文将探讨一种能在微机上用分子力学模拟手性金属配合物的新方法 ,该方法以CsChem3D中MM2为支持力场 ,通过搭建和优化配合物Δ ,Λ Co(phen) 2 dppz]3+获得其几何构型 ,并将其构型特征量与文献值或实验值进行比较以确定该方法的可靠性

| Abstract: | To our knowledge, coordination bond is not a typical value\|bond. If modeling methods and parameter sets are unfitted to relevant structures, that will lead to no\|bonds or scattered structures. In this paper, a new method that can be used to modeling chiral metal complex by molecular mechanics in a PC has been explored. In this new method through the building and energy minimization of chiral metal complexes the optimal conformations are obtained, which is carried out on the base of MM2 force field from Cs Chem3D Package. And then its conformation characteristic values are compared with the literature values or experiment values in order to confirm reliability of the method. |
