He(Iα) and He(IIα) photoelectron spectra of SnF2 and PbF2 in the gas phase and as condensed solids have been recorded and analysed. The assignments of the molecular spectra were based upon correlation with established assignments for the lighter Group 4 difluorides which are normally considered to be metastable species. A close similarity was noted between the gas-phase and solid-state spectra. In the spectra of gas-phase SnF2 features were identified corresponding to the presence of Sn2F4. No polymeric species were identified in the spectrum of PbF2. Valence d shell ionization was observed for all systems.
