E. Dumas et al., SYNTHESIS AND MOLECULAR-STRUCTURE OF A NEW ARSENIC RICH POLYOXOVANADIUM ANION, [ASIII8VIV6O26](4-), Chemical communications, (21), 1996, pp. 2437-2438
Reaction of arsenic(III) oxide with vanadate in aqueous solution under
reducing conditions leads to the formation of the molecular anion [(A
s8V60O26)-V-III-O-IV](4), built up from two semicircular fragments whi
ch fit into each other to form a cage structure.
