Molybdenum(IV) bromide, also known as molybdenum tetrabromide, is the
inorganic compound
In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemi ...

The reaction proceeds via the unstable molybdenum(V) bromide, which releases bromine at room temperature.
Molybdenum(IV) bromide can also be prepared by oxidation of molybdenum(III) bromide with bromine.
