The ruthenium(II) complexes [Ru(CF3CO2)2(CF3triphos)], [Ru2(μ-Cl)3(CF3triphos)2]Cl, [RuH(CH3CN)2(CF3triphos)](CF3SO3) and (Ru(CH3CN)3(CF3triphos)](CF3SO3)2 (CF3triphos = CH3C{CH2P(m-CF3C6H4)2}3) were prepared and characterized. The iridium complexes [Ir(COD)(CF3triphos)](+), [IrCl(CO)(CF3triphos)], [Ir(CO)2(CF3triphos)](+), [IrCl3(CF3triphos)] and [IrCl3-n(-)(MeCN)n(CF3triphos)](CF3SO3)n (n = 1, 2 and 3) were also prepared and characterized. The coordination chemistries of these two elements withCF3triphos and with the unsubstituted ligand CH3C{CH2P(C6H5)2}3 (Htriph os) are compared. It is shown that, relative to Htriphos, CF3triphos (a)stabilizes the iridium(I) relative to the iridium(III) oxidation state and (b) its cationic complexes are stronger Lewis acids.
