were carried out and the structures of the synthesized complex were optimized using density functional theory (DFT). The molecular geometry, the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO) energies and Mulliken atomic charges and molecular electrostatic potential (MEP) of the molecules are determined at the B3LYP method and standard 6-311++G (d,p) basis
摘要含有芳酰基席夫碱配体(L)的一般组成为[Ru(bpy)2(L)] Cl的新八面体钌(II)配合物(其中bpy =联吡啶,L = 4-((E)-(呋喃- 2-carboylimino)甲基)苯甲酸(L1),4-((E)-(4-甲氧基苯甲酰氨基)甲基)苯甲酸(L2)和4-((E)-(4-硝基苯甲酰氨基)甲基)苯甲酸(L3 ))已合成。这三种复合物均已通过各种物理化学和光谱学方法进行了表征。L1和L2的分子结构通过单晶X射线衍射法确定。红外研究表明,取代的芳酰hydr配体表现为单阴离子二齿O和N供体(L)通过偶氮甲氮和去质子化的酰胺氧与钌配位。进行了光物理和电化学研究,并使用密度泛函理论(DFT)优化了合成配合物的结构。分子几何结构,最高占据分子轨道(HOMO),最低未占据分子轨道(LUMO)能量以及分子的Mulliken原子电荷和分子静电势(MEP)是通过B3LYP方法和标准6-311 ++
