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

The title compound, AuBr(C₆H₁₁NS)]_n, formed through an Au^IIIAu^I reduction process, presents a polymeric structure including Au chains with alternating Au—Au distances of 3.0898 (8) and 3.1181 (8) Å. The coordination geometry is best described on the basis of linear AuBr(C₆H₁₁NS)] mol­ecules, which are associated into a one‐dimensional polymer via a common aurophilic interaction.
