Crystal structure of the unusual coordination polymer catena-poly[[gold(I)-μ-1,2-bis(diphenylphosphinothioyl)ethane-κ2 S:S′] dibromidoaurate(I)]

 In the title compound, {[Au(C26H24P2S2)][AuBr2]}n, the gold(I) centres of the cation are coordinated by the P=S groups of the disulfide ligands to form a chain polymer parallel to the c axis. Both independent gold atoms lie on the same twofold axis, and the midpoint of the H2C-CH2 bond lies on an inversion centre. The anions flank the polymeric chain; they are connected to it by short aurophilic interactions and C-H...Br contacts, and to each other by Br...Br contacts.
