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

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]⁺.^[3]
