The single crystal ESR and proton ENDOR of VO 2+ doped into magnesium acetate tetrahydrate have been studied at 20 K. The VO 2+ ion occupies Mg 2+ sites, replacing Mg 2+ together with one water molecule. Hyperfine tensors for the six protons in the three coordinating water molecules have been determined and their dipolar components used to construct a model of the proton geometry. The relation of the structure to that of {VO(H 2 O) 5 } 2+ in a Tutton salt and in frozen aqueous solutions of vanadyl sulphate is discussed.
