In the present research, the synthesis of some new nano–scale metal chelates of an aromatic azo ligand has been reported. Toluidine red was synthesized by azo-coupling reactions of o-nitro-p-methyl phenyl diazonium salt with 2-naphthol and then its metal complexes were prepared with bulk Ni and Ni/SiO2 nanofine composite on the different pH and with the optimized conditions. The structures of products in overall yields of 75- 85% were deduced from their Atomic absorption and their UV, IR and NMR spectral data. According to XRD data, nano-scaled Toluidine Red-Ni complexes have monoclinic configuration and SEM technique have shown the size of particles are less than 100 nm. Also, nano metal complexes were evaluated in vitro for their antibacterial and antifungal activities against some bacteria and fungi. They have shown high activity against all species of them.
