The iridium(III) complexes Ir(CO)(OH)(SO4)L2, L = PPh3, P(p-tolyl)3, have been prepared and shown to react with CO, yielding the iridium(I) species [Ir(CO)3L2+][HSO4-] (L = PPh3, P(p-tolyl)3) and CO2. The species [Ir(CO)3(PPh3)2+][HSO 4-]·1/3H2O crystallizes in the centrosymmetric rhombohedral space group R3 [C3i2; No. 148]. Cell parameters (for the hexagonal setting) are a = 40.938 (7) A?, c = 11.850 (2) A?, V = 17199 A?3, and Z = 18. Diffraction data (Mo Kα?, 2θ = 4.0-45.0°) were collected on a Syntex P21 diffractometer, and the structure was refined to RF = 6.1% for all 4772 unique data (RF = 4.2% for those 3673 data with |Fo| > 6.0σ (|Fo|)).
