Abstract: The title compound, [Mn₂Br₂O₂(C₁₃H₃₀N₆)₂], is the first crystallographically characterized Mn^III₂(-O)₂ complex with a bidentate imine ligand . The molecule lies on a crystallographic inversion centre and shows distorted square-pyramidal coordination of the Mn atoms by two guanidine N atoms, the two bridging O atoms and a terminal Br ligand. The crystal structure involves an intermolecular C-HBr hydrogen bond.
