Abstract

Single crystals of the tungsten (VI) oxide hydrate, Ba2WO5·H2O, were grown using a hydroxide hydroflux. The structure was determined by single crystal X-ray diffraction. Ba2WO5·H2O crystallizes in the space group P21/n with a = 7.6710(15) Å, b = 9.8538(20) Å, c = 8.5520(17) Å, and β = 111.838(30)°. The crystal structure is comprised of [W2O10]8− dimeric units that are connected to surrounding barium cations located in face-, edge-, and corner-shared 8- and 9-fold coordination environments; the water of crystallization is only bound to barium.
