(1,4,7-Trithiacyclononane)silver trifluoromethanesulfonate crystallizes in a tetrameric form from nitromethane, to give the title compound, [Ag-4(C6H12S3)(4)](CF3SO3)(4).2CH(3)NO(2). The complex cation consists of four [AgL](+) units (L is 1,4,7-trithiacyclononane), with four Ag-S-Ag bridges forming a cyclic tetramer. The almost planar Ag4S4 ring takes an octagonal form.
