Novel ruthenium-amidinate complexes, (eta(6)-C6H5R)Ru(eta(2)-amidinate)X (R = Me, OMe, F) (4) and [Ru(eta(2)-amidinate)(MeCN)(4)]+PF6- (5) are synthesized by photochemical displacement of the benzene ligand in (eta(6)-C6H6)Ru(eta(2)-amidinate)X (3) by arenes or MeCN. The acetonitrile ligands of 5 are easily replaceable by other a-donor ligands (L) such as pyridines, phosphines, and isocyanides to afford the corresponding derivatives, [Ru(eta(2)-amidinate)(MeCN)(n)(L)(4-n)(+)] PF6- (n = 1 or 2).
