Abstract: The title compound, (C₂₄H₂₀As)₂[Sn(C₃S₅)₃]·C₃H₆O, is a further example of a salt of the general form Q₂[Sn(dmit)₃] (dimit is 1,3-dithiole-2-thione-4,5-dithiolate), where Q, the onium counter-cation, is in this case [AsPh₄]⁺. As in all such compounds, the coordination of the Sn atom is in the form of a distorted octahedron, with Sn-S distances in the range 2.5310 (10)-2.5585 (12) Å provided by three chelating dmit ligands with bite angles in the range 81.59 (3)-87.42 (3)°.
