Tellurium Oxybromides

Several rather indefinite Tellurium Oxybromide derivatives have been described. The existence of the compound TeOBr₂, intermediate between TeBr₄ and TeO₂, is generally recognised. On heating it first melts and then decomposes, giving a distillate of the tetrabromide:

2TeOBr₂ = TeO₂ + TeBr₄.

On this decomposition depends the effectiveness of the suggested method for freeing crude tellurium tetrabromide from any oxybromide present in it.
