The asymmetric unit of the title coordination polymer consists of a dinuclear neutral complex molecule of formula [Cu2(C18H14Br4N2O2)2]n. One of the CuII ions is coordinated in a distorted square-planar geometry, whereas the other is coordinated in a distorted square-pyramidal geometry, the long apical Cu—O bond [2.885 (4) Å] of the square-pyramidal coordination being provided by a symmetry-related O atom creating a one-dimensional polymer along [010]. π–π stacking interactions [centroid–centroid distance = 3.783 (4) Å] and short interchain Br...Br interactions [3.6142 (12)–3.6797 (12) Å] are observed.
