Bis(tetra-phenyl-phospho-nium) bis-[N-(trifluoro-methyl-sulfon-yl)dithio-carbimato(2-)-κS,S']zincate(II)

The title salt, (C(24)H(20)P)(2)[Zn(C(2)F(3)NO(2)S(3))(2)], consists of a complex dianion and two tetra-phenyl-phospho-nium cations. The Zn(II) ion displays a distorted tetra-hedral coordination environment with four S atoms from two S,S'-chelated N-(trifluoro-methyl-sulfonyl-)dithio-carbimate anions. In the crystal, besides the ionic inter-action of the oppositely charged ions, inter-molecular C-H⋯O inter-actions between cations and anions are observed. One of the cations inter-acts with an inversion-related equivalent by π-π stacking between phenyl rings, with a centroid-centroid distance of 3.932 (4) Å.
