A dinuclear Ru( ii ) complex capable of photoinduced ligand exchange at both metal centers Academic Article uri icon


  • {[Ru(CH3CN)3]2(tppz)}(4+) (tppz = tetra-2-pyridylpyrazine) undergoes photoinduced CH3CN exchange with λirr ≥ 610 nm in H2O. In contrast, cis-{[Ru(tpy)(L)]2(bpm)}(4+) (tpy = 2,2':6',2''-terpyridine, bpm = 2,2'-bipyrimidine, L = CH3CN) is not reactive, but the complex with L = DMSO is photoactive. These complexes are potentially useful for the release of multiply caged drugs.
