Results of investigations in the following areas of research are reported: trimethylphosphine-substituted (pentamethylcyclopentadienyl)iridium complexes; protonation and deprotonation of (C/sub 5/(CH/sub 3/)/sub 5/)Ir(P(CH/sub 3/)/sub 3/)H/sub 2/; synthesis and characterization of poly-trimethylphosphine-(pentamethylcyclopentadienyl)iridium complexes; simulation of ''virtually coupled'' /sup 13/C NMR spectra of (C/sub 5/R/sub 5/)M(P(CH/sub 3/)/sub 3/)/sub x/L/sup n+/ species; preparation and reactions of tetrahydrido(pentamethylcyclopentadienyl)iridium: a novel iridium (V) polyhydride; (pentamethylcyclopentadienyl)iridium polyhydride complexes: synthesis of intermediates in the mechanism of formation of (C/sub 5/(CH/sub 3/)/sub 5/)IrH/sub 4/ and the preparation of several iridium (V) compounds; NMR spectra of (C/sub 5/(CH/sub 3/)/sub 5/)IrH/sub 2/SiMe/sub 3/Li(pmdeta) and (C/sub 5/(CH/sub 3/)/sub 5/)IrH/sub 3/Li (pmdeta): the first direct observation of resolved /sup 7/Li - /sup 1/H coupling. 116 refs., 13 figs., 9 tabs.
