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