The asymmetric unit of the title coordination polymer consists of a dinuclear neutral complex mol-ecule of formula [Cu(2)(C(18)H(14)Br(4)N(2)O(2))(2)](n). One of the Cu(II) 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)†à ] of the square-pyramidal coordination being provided by a symmetry-related O atom creating a one-dimensional polymer along [010]. π-π stacking inter-actions [centroid-centroid distance = 3.783†(4)†à ] and short inter-chain Br⋯Br inter-actions [3.6142†(12)-3.6797†(12)†à ] are observed.
