Abstract: | Two new zinc(II)-complexes, dithiocarbimato (Ph4P)2[Zn(CH3SO2N=CS2)2] (1) and trithiocarbimato (Ph4P)2[Zn(CH3SO2N=CS3)2] (2), were obtained in the crystalline form by the reaction of potassium N-methylsulfonyldithiocarbimate (RSO2N=CS2K2) with zinc(II) acetate dihydrate and tetraphenylphosphonium chloride in dimethylformamide. Both complexes crystallize in the monoclinic system. The central Zn(II) ion has a distorted tetrahedral coordination in both compounds. In 1 the dithiocarbimato ligand coordinates via two S atoms while in 2 the trithiocarbimato ligand coordinates via S and N atoms. Both complexes were also characterized by IR, 1 H NMR and 13C NMR spectroscopies. Compound 2 is the first example of a zinc(II)-trithiocarbimato complex. |
