The silver-rich ternary oxides Ag{sub 6}Si{sub 2}O{sub 7}, Ag{sub 10}Si{sub 4}O{sub 13}, Ag{sub 6}Ge{sub 2}O{sub 7}, and Ag{sub 10}Ge{sub 4}O{sub 13}, as well as Ag{sub 2}SO{sub 4}, have been investigated with photoelectron spectroscopy. The Ag 3d core level binding energies in all four ternary oxides were found to be identical with that of Ag metal, compared to the small negative chemical shift observed in AgSO{sub 4} and most other silver compounds. The MgK{alpha} and HeI valence band spectra are both dominated by Ag 4d emission; at the lower photon energy O 2p-derived states are also observed. There is some evidence for a direct Ag 4d-O 2p interaction.
