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.
