Abstract

The salts [Ru(XYCR)(PMe2Ph)4]PF6 (XY = OS, R = OEt; XY = S2, R = H), [Ru(XYCNMe2)(PMe2Ph)4]PF6 (XY = O2, OS, S2) and the neutral product [RuH(O2CNMe2)(PPh3)3] are formed by interaction of CO2, COS or CS2 with [RuH(PMe2Ph)5]PF6 or [RuH2(PPh3)4] in ethanol or ethanol/dimethylamine mixtures; the crystal structure of [Ru(O2CNMe2)(PMe2Ph)4]PF6 has been determined.
