Oxovanadium clusters are intersting both as moels of bulk magnets and in their own right. Results are presented suggesting that in Na 6 [H 6 V 12 O 30 F 2 ]·22H 2 O (see Figure) it is meaningful to decide which particular vanadium centers should be considered at 5⊕ and which as 4⊕. It is shown that in principle ist is possible to tune and design the topology, and thus the magnetic properties, of polyoxovanadates( IV/V ) by means of the template effect.
