catena-Poly­[bromo(ω-thio­capro­lactam-κS)­gold(I)](Au—Au)

The title compound, [AuBr(C 6 H 11 NS)] n , formed through an Au III →Au I reduction process, presents a polymeric structure including Au chains with alternating Au-Au distances of 3.0898 (8) and 3.1181 (8) A. The coordination geometry is best described on the basis of linear [AuBr(C 6 H 11 NS)] molecules, which are associated into a one-dimensional polymer via a common aurophilic interaction.
