The crystal structure of the title complex, [Cu₂Br₂-(C₉H₇N)₂(C ₁₈H₁₅P)₂], has been determined by X-ray diffraction. The molecule possesses a crystallographic centre of symmetry in which the four-membered Cu₂ (μ-Br)₂ ring is planar, as required by the symmetry, with a Br-Cu-Br angle of 95.83 (2)° and two Cu-Br distances of 2.520(1) and 2.573(1) A. The long Cu...Cu distance [3.414 (1) A] indicates the absence of direct bonding between the two Cu atoms. The coordination sphere of copper is a distorted tetrahedron, with the six angles around copper ranging from 95.83 (2) to 118.1 (1)°. The Cu-N and Cu-P distances are 2.065 (3) and 2.216 (1) A, respectively.
