Thus modified fluorides of Ag(III) and Ag(II) might possibly emerge as a novel family of superconducting materials, analogous in some ways to the well known oxocuprate superconductors. Indeed, sudden drops in the magnetic susceptibility of a large number of samples in the Be-Ag-F system have been observed recently, and attributed to superconductivity at temperatures ranging from 8.5 K to 64 K (W. Grochala, P. P. Edwards, unpublished results).

note

DFT computations indicate that the "ligand band" lies below the "metal band" in silver fluorides;[2] for example for AgF the energy difference is some 3 eV, similar to the experimental value of 2.5 eV.

note

The ionization cross-section of the F(2s) electrons is one order of magnitude smaller than that for the Ag(4d) ones, and the contribution from the former to the valence band is small, according to the calculations[2].

The "ligand band" progressively shifts to lower binding energies in the order AgF > AgCl > AgBr ≈ AgI, and simultaneously gains intensity, thus reflecting the increasing energy of the np orbitals of the nonmetal and their stronger mixing with the Ag(4d) orbitals.

The values listed in Table 6 of ref.[4] were normalized so that the sum of contributions is 100 %. Contributions from all silver valence orbitals (4d + 5s + 5p) was in fact taken in ref.[2]. However the contribution from Ag(5s + 5p) states to the valence band is computed to be small and can be neglected in the comparison that follows.
