Manganese pentacarbonyl bromide

Manganese pentacarbonyl bromide is an organomanganese compound with the formula BrMn(CO)5. It is a bright orange solid that is a precursor to other manganese complexes. The compound is prepared by treatment of dimanganese decacarbonyl with bromine:[1]

Mn2(CO)10 + Br2 → 2 BrMn(CO)5
