The title complex, [Cu 2 (C 22 H 20 Br 2 N 4 O 2 )(ClO 4 ) 2 ], was prepared by the condensation of 2,6-diformyl-4-bromo­phenol with 1,3-diamino­propane in the presence of copper(II) ions. The macrocyclic ligand shows an approximately planar structure except for the two propene groups in the macrocycle. The coordination polyhedron of each Cu atom can be described as distorted square pyramidal. The two Cu atoms are bridged by two phenolate O atoms of the macrocycle, with a Cu⋯Cu distance of 3.109 (2) Å.
