摘要: 以密度泛函理论和电负性均衡原理为基础,在原子-键电负性均衡模型中,利用最小二乘法,并结合自编程序,拟合确定了氢、碳、氮、硫以及铁(Ⅱ)等各种类型的原子及相关化学键区域的参数.利用上述参数计算了一些铁(Ⅱ)配合物的电荷分布,计算结果可以和从头算结果很好地相关联.

关键词: 原子-键电负性均衡模型, 铁(Ⅱ)配合物, 电荷分布

Abstract: Based on density functional theory and electronegativity equalization principle,the parameters of atoms and bonds in the model were determined by applying an atom-bond electronegativity equalization model and using a separated program,and through linear regression and least-squares optimization.By employing these parameters,the charge distributions of iron(Ⅱ) complexes were calculated.The results of calculation may be well relevant to those of ab initio method.

Key words: Atom-bond electronegativity equalization model(ABEEM), Iron(Ⅱ) complex, Charge distribution
