Abstract
N’((furan-2-yl) methylene) benzohydrazide (N-FMBH) and 2-(2-aminothiazol-4-yl) acetohydrazide (2-ATCH) were prepared and characterized by melting point and infra-red studies. Their complexes with some M(II) sulphates (M = Mn, Co, Ni and Cu) were synthesized and characterized by melting point, solubility, infra-red and electronic spectral studies. The ligands are mainly neutral bidentate donors ligating via the carbonyl O and the primary amino N (or the azomethine N in the case of N-FMBH). The nickel, manganese and cobalt complexes are octahedral while the copper complexes are square planar respectively. The ligands and complexes showed some activity against Bacillus subtilis, Staphlyococus aureus, Escherichia coli and Klebseila pneumonia.
