Synthesis, spectroscopic, electrochemical and luminescence studies of ruthenium (II) polypyridyls containing multifunctionalized 1,2,4-triazole as co-ligand

Ruthenium (II) 2,2´-bipyridyl and 1,10-phenanthroline complexes with 4- amino-3-hydrazino-5-mercapto-1,2,4-triazole (LH2) as co-ligand were synthesised and characterized by elemental analysis, IR, UV/Vis, 1H NMR spectra and FAB-mass data. The electrochemical and luminescent properties of the complexes were also studied.
