Abstract

A tungsten(VI) oxytetrachloride having a chemical purity of greater than 99.95%. The tungsten(VI) oxytetrachloride has a fraction of compounds selected from WCl6, WO2Cl2, WO3 and WO2, as defined as a ratio of a reflection having a highest intensity of one of WCl6, WO2Cl2, WO3 and WO2, (I(P2)100) in an x-ray diffraction pattern to a reflection having a highest intensity of the tungsten(VI) oxytetrachloride (I(WOCl4)100) in the x-ray diffraction pattern, expressed as I(P2)100/I(WOCl4)100, of less than 0.03.
