Aluminium monobromide

Aluminium monobromide is a chemical compound with the empirical formula AlBr. It forms from the reaction of HBr with Al metal at high temperature. It disproportionates near room temperature:
 * 6/n "[AlBr]n" → Al2Br6  +  4 Al

This reaction is reversed at temperatures higher than 1000 °C.

A more stable compound of aluminium and bromine is aluminium tribromide.
