A series of binuclear transition metal complexes of the type [M2(L)2X4)]·nH2O (where, M = Cu(II), Ni(II), Co(II) or Zn(II), X= Cl–/CH3COO– and L = ligand) of a Schiff base ligand derived from 1-amino-5-methyl-2,6-pyrimidine-dione and 2,3-butanedione have been synthesized and characterized by elemental analysis, molar conductance measurements, magnetic moment measurements, IR, UV-visible, 1H NMR, EPR and mass spectral studies. Electronic spectral data and magnetic moment values indicate octahedral geometry for all the metal complexes. In vitro antimicrobial activity of ligand and its metal complexes were also studied against bacteria (Bacillus subtilis and Escherichia coli) and fungi (Aspergillus niger and Aspergillus flavus) which show antimicrobial activity of ligand and binuclear metal complexes.
一系列 [M2(L)2X4)]·nH2O 类型的双核过渡金属配合物(其中,M = Cu(II)、Ni(II)、Co(II) 或 Zn(II),X= Cl–/合成了源自 1-氨基-5-甲基-2,6-嘧啶-二酮和 2,3-丁二酮的希夫碱配体(CH3COO– 和 L = 配体),并通过元素分析、摩尔电导测量、磁矩进行了表征测量、红外、紫外-可见、1H NMR、EPR 和质谱研究。电子光谱数据和磁矩值表明所有金属配合物的八面体几何形状。还研究了配体及其金属配合物对细菌(枯草芽孢杆菌和大肠杆菌)和真菌(黑曲霉和黄曲霉)的体外抗菌活性,显示配体和双核金属配合物的抗菌活性。
