Abstract: The novel monoprotonated decavanadate species [HV10O28]5- has been prepared and characterized. The title compound, tetrapotassium sodium hydrogendecavanadate decahydrate, crystallizes in the monoclinic system in space group P2/n, with the polyanion having twofold crystallographic symmetry. The protonated O atom in the polyanion was identified from the elongation of the V-O bond and the shortest O
O inter-polyanion distance. The H atom is disordered around a twofold axis that relates two hydrogen-bonded polyanions.
