Abstract

The dimeric iridium(III) hydride complexes [IrHCl(SAr′)(PAr3)2]2 where Ar = 4-CH3C6H4 or C6H5 and Ar′ = 4-CH3C6H4, 4-CH3OC6H4, 4-FC6H4, or C6H5 have been shown to react in halogenated solvents such as chloroform or 1,2-dichloroethane to form triply bridged dimeric hydrated complexes of the type, [H(Ar3P)2Ir(SAr′)2ClIr(PAr3)H]Cl•2H2O. When PAr3 = (4-FC6H4)3P, no triple bridge formation was observed. However, the dimeric complexes, [IrHCl(SAr′)(PAr3)2]2 including PAr3 = (4-FC6H4)3P all react with AgClO4 in acetone to form the complexes, [H(Ar3P)2Ir(SAr′)2ClIr(PAr3)2H]ClO4•x(CH3)2CO (x = 0–3). The isolation and characterization of these triply bridged dimeric iridium(III) hydrides are discussed.
