Tetraphenyl­arsonium cis-bis­[1,2-bis­(tri­fluoro­meth­yl)ethene-1,2-dithiol­ato]platinate(II)

In the title compound, (C(24)H(20)As)[Pt(C(4)F(6)S(2))(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 –CF(3) 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.
