characteristic. The single crystal structures of 1–5 have been established by X-ray crystallography. The Ru has pseudo-octahedral half sandwich “piano-stool” geometry. The complexes 1–5 have been found efficient for catalytic oxidation of alcohols with N-methylmorpholine-N-oxide (NMO) and transfer hydrogenation of ketones with 2-propanol (at moderate temperature 80 °C) as TON values are up to 9.9 × 103
