The ligand has been prepared from ω-chloroisonitrosoacetophenone and 1,4-phenylenediamine in the presence of NaHCO3. The ligand have a C=O group and an –NH–R group adjacent to the oxime group. The Ni(II), Cu(II) and Co(II) complexes of the synthesized ligand were prepared and their structures were identified using FTIR, UV-Vis spectral data, elemental analysis, thermal analysis and magnetic moment measurements. The metal-ligand ratios were found to be 3:2. The ligands were found to coordinate to the metal ions via the oxime nitrogen, oxime oxygen, one of the carbonyl group and amide nitrogen atoms. Thermal analyses data reveals that the water in the complexes was found to be non-coordinated to the metal ions. In the trinuclear structures, the metals have the tetrahedral environments.
配体是由ω-氯异亚硝基苯乙酮和 1,4-苯二胺在 NaHCO3 的存在下制备而成。配体上有一个 C=O 基团和一个邻近肟基团的 -NH-R 基团。利用傅立叶变换红外光谱、紫外可见光谱数据、元素分析、热分析和磁矩测量,制备了合成配体的 Ni(II)、Cu(II) 和 Co(II) 复合物,并确定了它们的结构。发现金属与配体的比例为 3:2。配体通过肟氮、肟氧、一个羰基和酰胺氮原子与金属离子配位。热分析数据显示,配合物中的水与金属离子不配位。在三核结构中,金属具有四面体环境。
