Abstract
Anew series of solid metal complexes of (Co+2, Ni+2, Cu+2, Zn+2, Cd+2,andHg+2) were prepared from the complexation reaction between the azo-schiff base ligand and azo compound. Azo-azomethine ligand was synthesized by reaction vaniline with (3-bromo aniline) to produce Schiff base in one step then reacted Schiff base with (2-amino acetophenone) to from azo-schiff base ligand in two step. This ligand and its complexes were characterize by (C.H.N) elemental analysis, FT-IR,Uv-vis, 1H-NMR,mass spectrum,molar conductance,Atomic absorption, magnetic moment measurements. From theobtained results the octahedral geometrical shape was proposed for all prepared complexes. All complexes show that non-electrolytes properties. The biological activity of the ligand and the mixture of ligand and their metal complexes prepared on two types of bacteria, one of which is positive for the Gram stain (G +), is (Staphylococcus) and Another Cram negative (G-) represented by bacteria (Escherichia coli).
