The complex [IrH2(IMe)2(PPh3)2]SbF6 (1) contains two iodomethane groups coordinated via the iodine atoms. The Ir-I-C angles are 105.5 (4) and 108.2 (5)°. The coordinated iodomethane is activated toward nucleophilic attack at the carbon atom by NEt3, the rate of which is enhanced by 104-105-fold relative to free MeI. Removing the hydride ligands with t-BuCH=CH2 leads to oxidative addition to give [MeIr(μ-I)(PPh3)2]2 (2). Crystal structures of 1 and 2 were determined.
