Mixed bromide-chlorides of tungsten(VI)
Abstract
The compound WOCl3Br, prepared by reaction of bromine gas with potassium tri-µ-chloro-hexachloroditungstate(III), K3W2Cl9, has been characterized. It was one of a mixture of products which were separated by fractional sublimation. Small deviations in the stoicheiometry were consistent with the formula WOClnBr4-n, and the compounds were isostructural with WOCl4 and WOBr4. X-Ray data and far-i.r. spectra are reported.
