Abstract: The title salt, (C₂₄H₂₀P)₂[Zn(C₂F₃NO₂S₃)₂], consists of a complex dianion and two tetraphenylphosphonium cations. The Zn^II ion displays a distorted tetrahedral coordination environment with four S atoms from two S,S'-chelated N-(trifluoromethylsulfonyl)dithiocarbimate anions. In the crystal, besides the ionic interaction of the oppositely charged ions, intermolecular C-HO interactions between cations and anions are observed. One of the cations interacts with an inversion-related equivalent by - stacking between phenyl rings, with a centroid-centroid distance of 3.932 (4) Å.
