X-Ray photoelectron and Mössbauer spectroscopy of triphenylphosphine–iridium complexes

Abstract

Ir 4f core binding energies and ¹⁹³Ir Mössbauer data have been recorded for a series of (PPh₃)₂Ir(CO)X-type complexes and found to be fairly insensitive to variation of X. The Ir 4f and N 1s photoelectron and Mössbauer spectroscopic results for several iridium–nitrosyl complexes containing iridium in different formal oxidation states with linear and bent Ir–N–O-groups are discussed.
