The<jats:bold>1</jats:bold>·MnBr<jats:sub>2</jats:sub>and<jats:bold>1</jats:bold>O·MnBr<jats:sub>2</jats:sub>complexes are occupationally disordered about general positions. Both complexes feature square-pyramidal coordination of the Mn<jats:sup>II</jats:sup>atoms. They are connected by weak N—H...Br hydrogen bonding into chains extending along [001]. The THF molecules are located between the layers formed by these chains. One THF molecule is involved in hydrogen bonding to an amine H atom.</jats:p>
