Abstract: The Cu atom in the title compound, [CuBr₂(C₇H₆N₂)₄], is surrounded by four N-heterocycles that define an N₄ square-planar geometry. The coordination geometry is distorted towards an elongated octahedron owing to the presence of the two Br^- anions, which are located at about 3 Å above and below the square plane. There are two independent molecules in the asymmetric unit, each with their Cu atom lying on an inversion centre.
