|Title:||A new mixed-ligand ruthenium(II) complex with RuN6 coordination sphere having weak π-accepting ligand|
Mukherjee, R N
|Abstract:||The preparation and properties of a hetero-chelate ruthenium(II) complex containing tridentate pyridylpyrazole ligand and an asymmetric tridentate nitrogenous ligand giving two different chelate rings are described. Cyclic voltammetric experiments in acetonitrile solutions reveal a quasi-reversible one-electron RUIII - RuII redox couple at 1.14V vs saturated calomel electrode (SCE). The diffusion coefficient for this quasi-reversible system has been estimated to be 7.41 x 10-6 cm2 s-1 on the basis of cyclic voltammetric experiments. A moderately good correlation has been obtained for a selected group of rethenium(II) complexes with weak π-accepting ligands.|
