hydrazide] and its metal (II) complexes of molecular formula [Co(H2L1)(L2)], [Ni(H2L1)(L2)], [Cu(H2L1)(L2)], [Zn(H2L1)(L2)], [Cd(H2L1)(L2)], where, L2 = 2,2′-Bipyridine-4,4′-dicarboxylic acid as co ligand were synthesized and characterised using various analytical techniques. Based on spectral analysis, the complexes are found to be square pyramidal and also the coordinating sites of the complexes are azomethine
席夫碱配体(H 2 L 1 ) [H 2 L 1 = (E)-2-羟基-N'-((2-羟基萘-1-基)-亚甲基)苯并酰肼]及其金属(II)配合物分子式[Co(H 2 L 1 )(L 2 )]、[Ni(H 2 L 1 )(L 2 )]、[Cu(H 2 L 1 )(L 2 )]、[Zn(H 2 L 1 )(L 2 )], [Cd(H 2 L 1 )(L 2 )], 其中, L 2 = 2,2'-联吡啶-4,4'-二羧酸作为共配体被合成并使用各种分析技术进行表征。基于光谱分析,发现配合物是方锥体,配合物的配位点是偶氮甲碱氮、来自席夫碱配体 (H 2 L 1 ) 的两个酚氧和来自 2,2'-Bipyridine-4 的两个氮,4'-二羧酸。配体和复合物的抗微生物活性是通过对细菌病原体和真菌菌株进行测试来确定的。所有合成的复合物都比游离螯合物对测试微生物的活性更高。根据我们的研究结果,DPPH 法
