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
disproportionate
In chemistry, disproportionation, sometimes called dismutation, is a redox reaction in which one compound of intermediate oxidation state converts to two compounds, one of higher and one of lower oxidation states. More generally, the term can ...

This reaction is reversed at temperatures higher than 1000 °C.
A more stable compound of aluminium and bromine is
aluminium tribromide
Aluminium bromide is any chemical compound with the empirical formula AlBrx. Aluminium tribromide is the most common form of aluminium bromide. It is a colorless, sublimable hygroscopic solid; hence old samples tend to be hydrated, mostly as al ...
