The title compound, [Au2Br2(C27H26P2)], features linearly coordinated Au-I atoms within P,Br-donor sets. The central portion of the molecule is practically planar as quantified by the Br-Au center dot center dot center dot Au-Br torsion angle of -169.9 (2)degrees. The P-Au-Br chromophores are twisted with respect to each other [dihedral angle = 52.3 (6)degrees]. The benzene rings on each P atom lie on either side of this plane. The Au atoms are positioned at the periphery of the molecule, which facilitates the formation of Au center dot center dot center dot Au interactions [3.2575 (11) angstrom] that result in the formation of supramolecular chains along the b-axis direction. The Au center dot center dot center dot Au interactions are responsible for the deviations from the ideal linear geometry for each Au atom.
