Mono- and homobi- nuclear Ru (II) complexes were prepared by the reaction of [Ru (bipy) ₂Cl₂] H₂O with 4-amino-3,5-DI (2-byridyl) -4H-1,2,4-triazole (adapt); ( 4-byridyl) -3,5-DI (2-byridyl) -4H-1,2,4-triazole (Pydpt), and 4-( 4-methylphenyl) -3,5-DI (2-byridyl) -4H-1,2,4-triazole (mpdpt). The products were characterized by elemental analysis,  IR, electronic and ¹H NMR spectral however molar conductance and their Redox chemistry has been investigated using cyclic –voltmeter have been studied. An octahedral structure has been tentatively proposed for the new complexes. All the complexes exhibit reversible, metal-based oxidation processes and reversible, bipy-based reduction process in the potential window investigated. . The metal complexes are more active than the parent ligands and exhibit mild to moderate antibacterial activity.
