Sulfido-bridged IrRh2 clusters derived from (hydrogensulfido)iridium complexes and dirhodium fragment. Comparison between hydrido-hydrogensulfido and bis(hydrogensulfido) systems
Treatment of [Rh(mu(2)-Cl)(cod)](2) (cod = 1,5-cyclooctadiene) with the hydrido-hydrogensulfido complex [Cp*IrH(SH)(PMe3)] (Cp* = eta(5)-C5Me5) in the presence of triethylamine afforded the hydrido-mono(sulfido) complex [Cp*Ir(PMe3)(mu(2)-H)(mu(3)-S){Rh(cod)}{RhCl(cod)}], whereas the corresponding reaction with the bis(hydrogensulfido) complex [Cp*Ir(SH)(2)(PMe3)] gave the bis(sulfido) complex [Cp*Ir(mu(3)-S)(2){Rh(cod)}(2)] with liberation of trimethylphosphine.
