摘要 采用ah initio HF及密度泛函(DFT)B3LYP方法对[Si(S2Ph)n]m± (n=1~3)的稳定结构以及结合能进行系统的理论计算,分析了该配合物体系 稳定存在的可能性,并运用完全均衡校正法对基函数重叠误差(BSSE)进行了校 正,同时对配合物分子轨道进行了分析,为实验研究提供了有参考价值的理论结 果. The calculation of stable structures and binding energy of [Si(S2Ph)n]m±(n=1~ 3) been performed by means of ah initio HF and DFT(B3LYP) methods in Gaussian 94 package with 3 - 21G and 6-31G basis sets. The basis set superposition error (BSSE) is cor- rected. The stability of the complexes are analyzed. Some froniter molecular orbital energies of [Si(S2Ph)n]m±(n=1~3)have been investigated. The results are useful for experiment.
