The hydroxylamine complexes [MH(NH2OH)P4]BPh 4 (M = Ru, Os) and [Ru(NH2OH)2P 4](BPh4)2 [P = P(OEt)3, PPh(OEt)2] were prepared by allowing the triflate species MH(K 1-OSO2CF3)P4 and [Ru(κ 2-O2SOCF3)P4]+ to react with an excess of hydroxylamine. The iridium complexes [IrCl2(NH 2OH)PL2]BPh4 [P = P(OEt)3, PPh(OEt)2; L = PPh3, AsPh3] and [IrH 2(NH2OH)(PPh3)3]BPh4 were also prepared by reacting the hydride species [IrHCl2PL 3] and [IrH3(PPh3)3] first with triflic acid and then with an excess of NH2OH. The O-iminoacylated hydroxylamine complexes [M{η2-NH=C(R)ONH2}P 4](BPh4)2 and [M{η 2-NH=C(R)ONH-(CH3)}P4](BPh4) 2 (M = Ru, Os; R = CH3, 4-CH3C 6H4) were prepared by allowing the nitrile complexes [M(RCN)2P4](BPh4)2 to react with hydroxylamine (NH2OH) or N-methylhydroxylamine [NH(CH 3)OH]. The compounds were characterised spectroscopically (IR, 1H, 13C and 31P NMR) and a geometry in solution was also established. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
