The authors have measured the Moessbauer spectrum of the adduct of chlorocarbonylbis(triphenylphosphine)iridium (CCTI) with buckminsterfullerene (C[sub 60]) and, for comparison, remeasured the spectra of both the parent compound CCTI and its adduct with tetracyanoethylene, CCTI-TCNE. Moessbauer spectra of the [sup 193]Ir 73 keV [gamma]-transition were taken at 4.2 K. The source was metallic [sup 193]Os, which, being hexagonal, exhibits a quadrupole splitting of about 0.48 mm/s. The individual lines of the quadrupole doublets of the studied samples are therefore not simple Lorentzians; this circumstance is taken into account in the fitting procedure. The full widths at half-maximum of the individual superimposed Lorentzian lines obtained by the least-squares fits are between 0.75 and 0.79 mm s[sup [minus]1] and thus but slightly larger than the natural line width of 0.60 mm s[sup [minus]1].
