Amavadin is a vanadium-containing anion found in three species of poisonous Amanita mushrooms: A. muscaria, A. regalis, and A. velatipes. Amavadin was first isolated and identified in 1972 by Kneifel and Bayer. This anion, which appears as a blue solution, is an eight-coordinate vanadium complex. A Ca2+ cation is often used to crystallize amavadin to obtain a good quality X-ray diffraction. Oxidized amavadin can be isolated as its PPh4+ salt. The oxidized form contains vanadium(V), which can be used to obtain an NMR spectrum.

Pervanadyl is jargon that has two meanings. Pervanadyl can refer to aquo complexes containing (). This pale yellow oxycation of vanadium(V) is the predominant vanadium(V) species in acidic solutions with pH between 0 and 2. Like permanganate, pervanadate features the metal in its highest oxidation state.
