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] The complex undergoes substitution by a variety of donor ligands (L), e.g. to give derivatives of the type BrMn(CO)3L2.

The complex adopts an octahedral coordination geometry.

[2] Manganese pentacarbonyl bromide is a precursor to the arene complexes [(η6-arene)Mn(CO)3]+.
