The electrochemical reaction of the bis‐bidentate Schiff base H 2 FTs [ N, N′ ‐bis(2‐tosylaminobenzylidene)‐1, 2‐diaminobencene] with cobalt, nickel, copper, zinc and cadmium, lead to the isolation of neutral [M(FTs)] complexes. All of them were characterized by elemental analyses, mass spectrometry, IR and 1 H NMR spectroscopy and magnetic measurements, where appropriate. Recrystallization of the nickel complex yields single crystals of [Ni(FTs)]·CH 3 CN ( 1 ). The x‐ray characterization shows a distorted square‐planar environment for the nickel atom, with the Schiff base acting as a tetradentate N 4 donor. Complex 1 can be described as a mononuclear single‐stranded helical compound, with spontaneous resolution of the P enantiomer upon crystallisation.
