He I and He II photoelectron spectra are reported for Os(eta-C6Me6)NBut, Os(eta1,4-(CHMe2)MeC6H4)NBut, and Ir(eta-C5Me5)NBut. Photoelectron bands are assigned using simple molecular orbital models for the complexes. The bonding of the osmium and iridium compounds shows similarities to that of the metallocenes but the metal a1 orbital is more destabilized in the case of the imido complexes.
