The title compound was synthesized by solvothermal method and its structure was characterized by elemental analysis and X-ray single crystal diffraction. The title compound belongs to the tetragonal system, space group I41 / acd with unit cell parameters of a = 1.444 3 (4), b = 1.444 3 (4), c = 3.855 0 Z = 32, Mr = 299.63 g / mol, Dc = 1.980 g.cm-3, μ = 6.10 mm-1, F (000) = 4672, R1 = 0.029, wR2 = 0.079, S = 1.05. In the title compound, Cu + coordinated with one N atom of two 4,4’-bipyridines and two terminal bromine atoms respectively to form a tetrahedral coordination geometry. The distance between Cu ... Cu in the molecule is 0.282 95 (13) nm. In the a + c axis direction, a two-dimensional layered grid is formed by 4,4’-dipyridyl bridging, and the layers and layers are interpenetrated to form a three-dimensional structure.
