Abstract Oxovanadium clusters provide novel examples of large magnetic clusters, which may showin nuce the typical behavior of bulk magnetic materials. The paper reviews the magnetic properties of V15, comprising fifteen oxovanadium(IV); V14, comprising fourteen oxovanadium(IV); V3+1, comprising three localized oxovanadium(IV), six localized oxovanadium(V), and one oxovanadium(IV) delocalized over three sites; V4+2 and V4+4 which comprise four localized and two and four delocalized oxovanadium(IV), respectively. The different observed magnetic behaviors are discussed on the basis of several models of different sophistication.
