The solid metal Complexes of Cu (II), Ni (II), Fe (III), Co (II) Mn (II) and Cd (II) with novel Schiff base ligand derived from DHA (3-acetyl-4-hydroxy-6-methyl-2H-pryan-2-one) and aromatic primary amine, 4-amino-1,2,4-triazole were synthesized and characterized by elemental analysis , FTIR , UV-VIS and 1HNMR spectroscopic techniques. The signals of the 1HNMR spectrum and important bands in IR spectra are considered and discussed in relation to the molecular structure of the ligand. The UV-VIS absorption bands are assigned to corresponding electronic transitions and are also studied by the magnetic studies. The biological (Anti-bacterial and Ant-fungal) activity of ligand and metal complexes have been screened in vitro against Bacillus subtilis, Staphylococcus aureus, Aspergillus niger, and Candida albicans. Schiff base ligand, as well as all metal complexes, have shown harmonious biologically activities.
