Abstract: In the title compound, (C₂₄H₂₀As)[Pt(C₄F₆S₂)₂], the cation lies on a twofold rotation axis while the anion has crystallographic inversion symmetry. The Pt^II ion is in a slightly distorted square-planar coordination environment. The F atoms of both unique -CF₃ groups are disordered over two sets of sites, the ratios of refined occupancies being 0.677 (15):0.323 (15) and 0.640 (16):0.360 (16). The crystal structure is the first to date of a monoanionic [Pt(tfd)₂]^- species [tfd is 1,2-bis(trifluoromethyl)ethene-1,2-dithiolate] with a non-redox-active cation.
