New azo reagent was synthesized by reaction dizonium salt of Para aminobenzoic acid with Pyrogallol, also prepared three Chelate complexes of this reagent with the metal ions of Co(II), Ni(II), and Ag(I). This reagent was characterized by FTIR(Fourier Transform Infrared), UV. Visible spectrophotometer, FESEM and HNMR proton. The antibacterial activities of the compounds were studied and evaluated using gram positive and negative gram bacteria. The purity of the dye was checked by thin layer chromatography (TLC) using solvent system (Toluene-Methanol) (2:3).The melting point of the purified dye was measured in an open capillary tube. The results showed that some of these compounds have high levels of antibacterial activity.
