PPh4[SnCl3] reacts with Na2S4 in acetonitrile to give the title compound as one of the products. Its crystal structure was determined by X-ray diffraction (R = 0.071 for 3288 reflexions). Crystal data: monoclinic, P21/C, Z = 4, a = 1301.2(3), b = 1139.1(2), c = 3476.2(7) pm, β = 97.82(3)°· (PPh4)2[Sn(S4)3] is isotypic with (PPh4)2[Sn(Se4)3] and contains [Sn(S4)3]2- ions in which three tetrasulfido groups are chelating an octahedrally coordinated tin atom.
