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.
