Carbonyls iridium

By contrast, reaction of XeFi with the iridium carbonyl complex cation [Ir(CO)3(PEt3)2] in CH2CI2 results in addition across one of the Ir-CO bonds to give the first example of a metal fluoroacyl complex ... [Pg.895]

Wickman and Silverthom [276] have investigated bond properties in molecular adducts of the planar Vaska type compound frans-h s(triphenyl-phosphine)iridium carbonyl chloride, IrCl(CO) ((C6H5)3P)2, with small molecules such as H2, O2, CI2, I2, CH3I, and HCl. They essentially observed a decrease of the isomer shift in the following series of adduct molecules XY H2 > HCl > CH3J > O2 > I2 > CI2,... [Pg.325]

Iridium carbonyl clusters of several nuclearities (2, 4 and 6) have been prepared by a controlled carbonylation of [lr(CO)2(acac)] complex adsorbed in the cages of a NaY zeolite. Then, decarbonylation of the clusters gave rise to lr2, lr4 and Ir frames. Studies of the dependence of the catalytic activity on the size of the iridium frames in NaY zeolites show that there is no simple explanation for the variation in catalytic performance in ethene hydrogenation with cluster size [208].
