Abstract: (1,4,7-Trithiacyclononane)silver trifluoromethanesulfonate crystallizes in a tetrameric form from nitromethane, to give the title compound, [Ag₄(C₆H₁₂S₃)₄](CF₃SO₃)₄·2CH₃NO₂. 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.

Formula: [Ag₄(C₆H₁₂S₃)₄](CF₃SO₃)₄·2CH₃NO₂
