On the covalency of silver-fluorine bonds in compounds of silver(I), silver(II) and silver(III).
- Unconventional covalence: For the higher silver fluorides the silver-fluorine chemical bonding is significantly covalent, in contrast to the conventional "ionic" picture most frequently used in the chemistry of inorganic fluorides. For KAgF4, an Ag(III) fluoride, the Ag(4d) states (see picture) are more within the "ligand band" (60%) than within the "metal band" (40%) reflecting significant covalency of the Ag-F bond, and an electronic band with significant hole production within the anionic F(2p) states.
