The complex molecule of the title compound, [Cu3Br(C22H28N4O2)(2)]Br center dot 2C(3)H(7)NO, contains three copper atoms, two of which are five-coordinate within a square-pyramidal environment and linked by a bridging Br atom occupying the apical position in each square pyramid. The remaining Cu atom is four-coordinate but with considerable tetrahedral disortion [the dihedral angle between the two chelate planes is 69.21 (7)degrees]. There are two molecules of dimethylformamide (DMF) present as solvent molecules, one of which is disordered over two equivalent conformations with occupancies of 0.603 (5) and 0.397 (5). The amine H atoms are involved in both inter-and intramolecular hydrogen-bonding interactions with the Br and O atoms of the cation, as well as with the O atom of the ordered DMF molecule.
