Abstract The electrochemical oxidation of anodic metal (zinc or cadmium) in acetonitrile solution of the potentially chelating Schiff base N,N ‐(dithiodiethylenebis(aminylydenemethylydene)bis(1,2‐phenylene)ditosylamide (H 2 L) afforded stable complexes of empirical formula [ML]. The crystal and molecular structures of [ZnL]·CH 3 CN ( 1 ) and [CdL] ( 2 ) have been determined by X‐ray diffraction. In both complexes the metal atom is in a distorted tetrahedral environment with the Schiff base acting as a tetradentate N 4 donor. Spectroscopic data for the complexes (IR, ES MS and 1 H NMR spectra) are discussed and related to the structural information.
