In the presence of a bidentate chelate containing two convergent nitrile groups, Ru(phen)2L2+ (L = sterically hindering aromatic diimine ligand; phen = 1,10-phenanthroline) undergoes a photochemical reaction leading to quantitative replacement of the diimine by the bis-nitrile ligand; the reverse reaction takes place upon heating, also quantitatively.
