Abstract: Two new compounds of the general formula: (Ph4P)2[Zn(RSO2N@CS2)2], where R¼C6H5 (1) and 4-CH3C6H4 (2) were obtained in crystalline form by the reaction of the appropriate potassium N-R-sulfonyldithiocarbimate (RSO2N@CS2K2) with zinc(II) acetate dihydrate in dimethylformamide. The compounds crystallise in the centrosymmetric space group of the triclinic system with Z ¼ 2. The single crystal X-ray analysis showed a similarly distorted tetrahedral configuration around the zinc(II) cation due to the bidentate chelation by two sulfur atoms of the N-R-sulfonyldithiocarbimate ligands. Ionic interaction between oppositely charged moieties, i.e., the bis(N-R-sulfonyldithiocarbimato)zincate(II) dianion [Zn(RSO2N@CS2)2]2_ and tetraphenylphosphonium cation Ph4Pþ and van der Waals interactions determine the crystal packing motif. The IR data are consistent with the formation of zinc–dithiocarbimate complexes. The 1H NMR and 13C NMR spectra showed the expected signals for the tetraphenylphosphonium cation and the dithiocarbimate moieties.
