A new Schiff base ligand was synthesized by reaction of salicylaldehyde with 1,6-bis(4-chloro-2-aminophenoxy)hexane. Then the Schiff base complexes were synthesized by metal salts and the Schiff base. The metal to ligand ratio of metal complexes was found to be 1:1. The Cu(II) complex is proposed to be square planar and the Co(II), Ni(II), Mn(II) and Zn(II) complexes are proposed to be tetrahedral geometry. The Ti(III) and V(III) complexes are proposed to be a capped octahedron in which a seventh ligand has been added to triangular face. The complexes are non-electrolytes as shown by their molar conductivities (ΛM). The structure of metal complexes is proposed from elemental analysis, FT-IR, UV-vis, magnetic susceptibility measurements, molar conductivity measurements, Mass Spectra and thermal gravimetric analysis. In addition antimicrobial and antioxidant studies, cyclic voltammetry of the complexes, theoretical 1H NMR and HOMO-LUMO energy calculations of the new di-functional ligand were done.
通过水杨醛与1,6-双(4-氯-2-氨基苯氧基)己烷反应合成了一种新的席夫碱配体。然后通过金属盐与席夫碱合成了席夫碱配合物。发现金属配合物的金属与配体比例为1:1。推测Cu(II)配合物为平面正方形，Co(II)、Ni(II)、Mn(II)和Zn(II)配合物为四面体几何构型。推测Ti(III)和V(III)配合物为盖帽八面体，其中在三角形面上添加了第七个配体。如摩尔电导率(ΛM)所示，配合物为非电解质。通过元素分析、傅里叶变换红外光谱(FT-IR)、紫外可见光谱(UV-vis)、磁化率测量、摩尔电导率测量、质谱和热重分析推测金属配合物的结构。此外，还进行了抗菌和抗氧化研究、配合物的循环伏安法、新型双功能配体的理论1H NMR和HOMO-LUMO能量计算。
