ABSTRACT: Single crystals of the hydrated potassium orthovanadate phases K3(VO4)·0.56H2O, tripotassium orthovanadate 0.56-hydrate, and K3(VO4)·4H2O, tripotassium orthovanadate tetra-hydrate, were isolated during the processing of products obtained under hydro-flux conditions. The asymmetric unit of K3(VO4)(H2O)0.56 (space group P1, Z = 12) comprises six formula units of K3(VO4) and five water mol-ecules of crystallization. The complex crystal structure is made up of isolated [VO4]3- tetra-hedra connected via K+ cations exhibiting coordination numbers between 6 and 8. The structure is consolidated by the formation of
