Fe(II), Co(II), Ni(II), Cu(II), and Zn(II)]. The molecular structures of as-synthesized Schiff bases were explicitly confirmed by physical, spectral, analytical and computational studies. Quantum chemical calculations based on density functional theory (DFT) were performed at B3LYP/6-311+G(d.p) level to explore the optimized geometrical structures, molecular electrostatic potential (MEP), Mulliken atomic
该项目的目的是通过设计和合成两个单席夫碱4- [(5-氨基-1H-1,2,4-三唑-3-基)亚氨基]甲基苯-1 引入新型生物活性化合物。,3-二醇(L 1)和2- [(5-氨基-1H-1,2,4-三唑-3-基)亚氨基]甲基} -6-甲氧基苯酚 (L 2)和一个双席夫碱,2,2'-1H-1,2,4-三唑-3,5-二基双[亚硝基甲基亚甲基]}双(6-甲氧基苯酚) (L 3)以及它们的过渡金属络合物[VO(IV),Cr(III),Mn(II),Fe(II),Co(II),Ni(II),Cu(II)和Zn(II)]。合成后的席夫碱的分子结构已通过物理,光谱,分析和计算研究明确证实。在B3LYP / 6-311 + G(dp)级别上进行了基于密度泛函理论(DFT)的量子化学计算,以探索优化的几何结构,分子静电势(MEP),穆里肯原子电荷(MAC)和前沿分子轨道( FMO)分析合成后的配体。对于配体(L
