The reversible conversion of co-ordinated nitrosyl into co-ordinated nitrite in 2,2′-bipyridyl complexes of ruthenium(<scp>II</scp>)

Abstract

Nitric oxide bonded to ruthenium in 2,2′-bipyridyl complexes of ruthenium(II) exists as co-ordinated nitrosyl in acidic solution, but as co-ordinated nitrite in basic solution, and the interconversion between the two forms is reversible.
