| Abstract: | Novel dihydroiridium(III) complexes containing mono- and bi-dentate sulfur ligands have been isolated. The cationic complexes Ir(COD)L2]ClO4 (COD = 1,5-cyclooctadiene, L = tetrahydrothiophene (tht) or trimethylene sulfide (tms); L2 = (CH3S)2(CH2)3 (dth)), Ir(COD)(L-L)]2(ClO4)2 (L-L = 1,4-dithiacyclohexane (dt) or (t-BuS)2(CH2)2 (tmdto)) and Ir(CO)2(tmdto)]2-(ClO4)2 react with H2 to give the corresponding iridium(III) dihydrides: IrH2COD)L2]ClO4 (Ia: L = tht, Ib: L = tms, Ic: L2 = dth), IrH2(COD)-(L-L)]2(ClO4)2 (IIa: L-L = tmdto, IIb: L-L = dt) and IrH2(CO)2(tmdto)]2-(ClO4)2 (III). The 1H NMR chemical shifts and ν(IrH) data are discussed. |
