Abstract: 2 (-p-Nitrobenzoyl) Thiobenzimiazole complexes of Pd (II), Rh (III), Pt (IV) and Au (III) ions were prepared by thermal method. The ligand and the complexes were isolated and characterized in solid state by using FT-IR, UV-Vis spectroscopy, NMR, flame atomic absorption, elemental analysis C. H. N. S, magnetic susceptibility measurements, melting points and conductivity measurements. The nature of complexes in liquid state was studied by following the molar ratio method which gave results approximately identical to those obtained from isolated solid state, also, stability constant of these complexes were studied and found that they were stable in molar ratio 11. All complexes have a sequar planner geometry except Pt (IV) complex has an octahedral. A theoretical treatment of ligand and its metal complexes in gas phase were studied using HyperChem-8 program and Gaussian program (GaussView Currently Available Version (5.0.9) along with Gaussian 09 which was the latest in the Gaussian series of programs). The antibacterial activity of the prepared complexes have been determine and compared with that of the ligand and the standard metronidazole.
