Powder Diffraction Study at 530 K. — A yellow crystalline powder of the title com-pound is prepared by an acidic steam hydrothermal route starting with ZrOCl2, W7O24, NH4VO3, and 6M HCl (autoclave, 473 K, 20 h; annealing at 873 K, 2 h). ZrW1.8V0.2O7.9 crystallizes in the cubic space group Pa3 with Z = 4. The average structure is similar to that of β-ZrW2O8 with substitution occurring only at one of the W sites. — (CHEN, X.; TAO, J.; MA, H.; ZHAO*, X.; Acta Crystallogr., Sect. C: Cryst. Struct.
