In this study, the Schiff base ligand trans-N,N'-bis[(2,4-dichlorophenyl) methylidene] cyclohexane-1,2-diamine (L) and its copper(II), nickel(II) and palladium(II) transition metal complexes were prepared and characterized by the analytical and spectroscopic methods. The (1)H((13)C) NMR spectra of the ligand and its diamagnetic complexes were recorded in DMSO-d(6) solvent and obtained data confirm that the nitrogen atoms of the imine groups coordinated to the metal ions. Electrochemical properties of the ligand and its metal complexes were investigated in the DMF solvent at the 100 and 250 mVs(-1) scan rates. The ligand and metal complexes showed both reversible and irreversible processes at these scan rates. The single crystal of the ligand (L) was obtained from MeOH solution, and its crystal structure was determined by X-ray diffraction. The C-Hcdots, three dots, centeredCl hydrogen bonding interactions in the molecule were seen which increase the stability of the crystal structure. The antimicrobial activity studies of the ligand and its metal complexes were carried out by using the various bacteria and fungi.
在这项研究中，制备并通过分析和光谱方法对席夫碱配体反式-N,N'-双[(2,4-二氯苯基)亚甲基]环己烷-1,2-二胺（L）及其铜(II)、镍(II)和钯(II)过渡金属配合物进行了表征。在 DMSO-d(6)溶剂中记录了配体及其反磁性配合物的 (1)H((13)C) NMR 光谱，得到的数据证实了亚胺基团的氮原子与金属离子配位。在 100 和 250 mVs(-1)的扫描速率下，研究了配体及其金属配合物在 DMF 溶剂中的电化学性质。在这些扫描速率下，配体和金属配合物均表现出可逆和不可逆过程。配体（L）的单晶从 MeOH 溶液中获得，并通过 X 射线衍射确定了其晶体结构。在分子中观察到 C-H···、三点、中心 Cl 氢键相互作用，这增加了晶体结构的稳定性。通过使用各种细菌和真菌对配体及其金属配合物进行了抗菌活性研究。
