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 KAgF 4 , 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 AgF bond, and an electronic band with significant hole production within the anionic F(2p) states.
