Di-μ-bromo-1:2κ⁴Br-bis(quinoline)-1κN,2κN-bis(triphenylphosphine)-1κP,2κP-dicopper(I)

The crystal structure of the title complex, [Cu₂Br₂(C₉H₇N)₂(C₁₈H₁₅P)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) Å. The long Cu...Cu distance [3.414 (1) Å] 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) Å, respectively.
