The two title compounds, prepared from VOC1 3 and the silver salts of pivalic and benzoic acids , are interesting models for the structure of the vanadium center in haloperoxidases from marine brown algae. The V v center in crystalline pivalate complex 1 displays pentagonal‐bipyramidal coordination. However, IR and 51 V NMR data suggest that in solution the vanadium atom is only sixfold coordinated. The second title substance, which is hexanuclear, is an entirely new type of multinuclear oxovanadium compound with a twist‐boat V 6 structure.
