Oxidation of trans-[RuCl(NO)(py)4]2+ with NaClO gives oxo complex of RuIV, trans-[RuCl(O)(py)4]+, with bond breaking of the metal-nitrosyl ligand. An X-ray structural study revealed that the complex has a much longer Ru–O bond distance (1.862(8) Å) than those of known mono-oxo complexes. A facile reactivity of the oxoruthenium(IV) complex was observed: with methanol methoxo complex, trans-[RuCl(OMe)(py)4]+, was formed. With PPh3, a two-electron transfer process was indicated by the formation of Ph3PO.
