N2 - Treatment of [Ru(η6-C6Me6)Cl 2]2 with AgOTf (OTf- = triflato) followed by K[N(R2PQ)2] gave the 16-electron complexes [Ru(η6-C6Me6){η2-N(R 2PQ)2}][OTf] [Q = S, R = Ph (1) or iPr (2); Q = Se, R = Ph (3) or iPr (4)] which were isolated as airstable blue or dark green crystals. For complex 1, when the crude product was recrystallised from CH 2Cl2/hexane in air, orange crystals of [Ru(η6-C6Me6){η3-N(Ph 2PS)2}][OTf] (1a) were isolated as a minor product. The reaction of compound 1 with ammonia, hydrazine hydrate and 4,4′-bipyridyl (4,4′-bpy) gave the 18-electron adducts [Ru(η6-C 6Me6){η2-N(Ph2PS) 2}L][OTf] [L = NH3 (5), N2H4 (6)] and dinuclear [{Ru(η6-C6Me6) [η2-N(Ph2PS)2]}2(μ-4, 4′-bpy)][OTf]2 (7), respectively. Treatment of compound 2 with Li[BEt3H] and NaBH4 afforded the ethyl [Ru(η6-C6Me6){N(iPr2PS) 2}Et] (8) and hydride [Ru(η6-C6Me 6){η2-N(iPr2PS)2}H] (9) compounds, respectively. Formal potentials for Ru[N(R2PQ) 2] complexes have been determined. The structures for complexes 1, 1a, 5, 6, 8 and 9 have been established by X-ray crystallography.
