Abstract
Fly agaric accumulate vanadium in the form of amavadin, whose structure has been elucidated (see picture for the crystal structure). Amavadin contains one VIV center coordinated to two (S,S)-hidpa3− ligands (H3hidpa=2,2′-(hydroxyimino)dipropionic acid) through one η2-NO− group and two unidentate carboxylato groups from each ligand. The arrangement of the two η2-NO− groups leads to a chiral vanadium center, which has been characterized in both the Λ and Δ forms. The carboxylato groups of the amavadin anions bind cations, for example, Ca2+ ions, and/or become involved in hydrogen bonding.Keywords
