In the title complex, [CuBr(2)(C(6)H(4)N(2)Se)(2)], the Cu(II) ion is tetra-coordinated by two bromide anions and two N atoms in a distorted square-planar geometry. The two essentially planar 2,1,3-benzoselenadiazole ligands [maximum deviations = 0.012 (2) and 0.030 (2) Å] are approximately coplanar [dihedral angle = 6.14 (6)°]. In the crystal, short inter-molecular Se⋯Br, Se⋯N and N⋯N inter-actions are observed. These short inter-actions and inter-molecular C-H⋯Br hydrogen bonds link the complex mol-ecules into two-dimensional arrays parallel to the ac plane.
