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 [(η<sup>6</sup>-arene)Mn(CO)<sub>3</sub>]+.[3]
