A new Mannich baseN-[morpholino(phenyl)methyl]acetamide (MBA), was synthesized and characterized by spectral studies. Chelates of MBA with cobalt(II), nickel(II) and copper(II) ions were prepared and characterized by elemental analyses, IR and UV spectral studies. MBA was found to act as a bidentate ligand, bonding through the carbonyl oxygen of acetamide group and CNC nitrogen of morpholine moiety in all the complexes. Based on the magnetic moment values and UV-Visible spectral data, tetracoordinate geometry for nitrato complexes and hexacoordinate geometry for sulphato complexes were assigned. The antimicrobial studies show that the Co(II) nitrato complex is more active than the other complexes.
一种新的Mannich碱N-[吗啡啉(苯基)甲基]乙酰胺(MBA)已合成并通过光谱研究进行了表征。MBA与钴(II),镍(II)和铜(II)离子形成的螯合物经元素分析、红外光谱和紫外光谱研究进行了表征。在所有配合物中,MBA被发现作为一个双齿配体,通过乙酰胺基的羰基氧和吗啡啉部分的CNC氮进行配位。根据磁矩值和紫外可见光谱数据,为硝酸盐配合物指定了四配位几何结构,为硫酸盐配合物指定了六配位几何结构。抗微生物研究表明,Co(II)硝酸盐配合物比其他配合物更活性。
