and solvent on the absorption spectra of both ligands and complexes was determined. IR spectra show that the ligands act in a bidentate manner and coordinates N4 donor groups of the ligands to Ni(II), Cu(II) and Co(II) ions. The detection of H-bonding (O-H⋯O) in the [M(LH)2] metal complexes by IR spectra supported the square-planar MN4 coordination of mononuclear complexes. The antimicrobial activities
合成了两个新颖的邻位二肟配体,它们含有(4-甲氧基苯甲醛硫代半碳酰胺酮乙酰胺肟(L(1)H2)或4-乙氧基苯甲醛硫代半碳酰胺酮乙酰胺肟(L(2)H2))硫代半碳酰胺酮单元,并使用(1)H NMR,(13)C NMR,HMQC,MS,红外和UV-VIS。光谱学,元素分析和磁化率测量。还合成了L:1H2和L(2)H2的金属:配体比为1:2的单核镍(II),铜(II)和钴(II)配合物。确定了pH和溶剂对配体和配合物的吸收光谱的影响。红外光谱表明,配体以双齿方式起作用,并且将配体的N4个供体基团配位为Ni(II),Cu(II)和Co(II)离子。红外光谱检测[M(LH)2]金属配合物中的H键(OH = O)支持单核配合物的方形平面MN4配位。使用圆盘扩散法评估了化合物L(1)H2,L(2)H2及其Ni(II),Cu(II)和Co(II)配合物对12种细菌和4种酵母的抗菌活性。还确定了对7种细菌和
