Tetraphenyl-arsonium cis-bis-[1,2-bis-(tri-fluoro-meth-yl)ethene-1,2-dithiol-ato]platinate(II).

ABSTRACT: 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-(trifluoro-meth-yl)ethene-1,2-dithiol-ate] with a non-redox-active cation.
