Crystal structure of the unusual coordination polymer catena-poly[gold(I)-μ-1,2-bis­­(di­phenyl­phosphino­thio­yl)ethane-κ2S:S′] di­bromido­aurate(I)]1

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.
