(17) The relative intensities of these two bands in solution and in the
solid state are reversed. Caution is recommended when interpreting
infrared data for metal hydrido carbonyl complexes due to coupling of
the νMH and νCO modes. For 3b and [4b]+ this might have been
expected to be minimal, given the crystallographically confirmed cis-
IrH(CO) geometry: Vaska, L. J. Am. Chem. Soc. 1966, 88, 4100.
(18) Hydride abstraction was also achieved, albeit less cleanly, using
either [Ph3C]PF6 or HPF6.
CIF files giving crystallographic data for 1a (CCDC 898434),
2a (CCDC 898436), 3b (CCDC 898439), and [4b][PO2F2]
(CCDC 898440) and text giving synthetic procedures and
spectroscopic and analytical data for the compounds described.

are able to reversibly coordinate PPh3 could also account for the
slower rate of formation of 2a.
