The preparation and characterization of the complex trans-Ir(?-CH2CN)(CO)(PPh3)2 are described.Like the isoelectronic and isostructural Vaska's complex, this iridium(I) derivative undergoes reactions with many simple molecules (CO, O2, HClO4, CH3I and H2) and is the precursor of a variety of novel iridium compounds whose stereochemistry has been assigned by IR and 1H NMR spectroscopy.Notably, the reaction with CH3I affords an unusually stable iridium(III) complex containing two metal-carbon ? bonds, while the cis-addition of hydrogen appears to follow a stereochemical pathway leading uniquely to the formation of a rare dihydrido derivative having the phosphine ligands cis to each other and trans to H.
