Abstract
In order to understand the behaviour of various azo-compounds and Schiff bases like p-aminoazobenene, diazoaminobenzene, p-nitrobenzene-azo-salicylic acid (sod slat) {2-[4-(dimethyl-amino) phenyl-azo] benzoic acid}, benzylidene-aniline, o-hydroxy benzylidene-p-tolidene, m-hydroxy-benzylidene aniline, p-hydroxy benzylidene-aniline, o-methoxy-benzylindene-aniline with different transition metal cations. E.g Cu++, Ag+, Au++, Zn++, Cd++, Hg++, Ni++, Pd++, Pt++ and Co++, the complexes were synthesized. The stoichiometric method of continuous variation. The stability constants of these metal complexes were also calculated by the same method.

The complexes were characterized by the metal analysis. The thermal stabilities of chelates were determined by thermal gravimetric and differential thermal analysis(TGA/DTA) techniques. The antibacterial and antifungal activities of chelates were tested against Agrobacterium tumefaciens (25,24) Pseudomonas aerogenosa (2556), Pseduomonas putida (2569), Bacillus subtilis, Bacillus thruingiensis, Corynebacterium petrophilum (2513) and Ascochyta rabiei (isolate NA-5) by Agar well plate method
