The electrochemical reaction of the bis‐bidentate H 2 ABATs Schiff base [H 2 ABATs = N , N′ ‐bis(2‐tosylaminobenzylidene)‐2‐aminobenzylamine] with manganese, iron, cobalt, nickel, copper, zinc and cadmium was investigated. The reaction cell yields products of empirical formula M(ABATs). X‐ray diffraction studies show that [Mn(ABATs)]·0.75H 2 O ( 1 ), [Fe(ABATs)]·0.75H 2 O ( 2 ), [Ni(ABATs)]·0.75H 2 O ( 3 ), [Cu(ABATs)]·0.5H 2 O ( 4 ) and [Zn(ABATs)]·0.75H 2 O ( 5 ) are mononuclear distorted tetrahedral helical complexes in the solid state. Complexes 1 and 2 confirm the ability of this type of ligand to dictate the geometry around the metal centre, as is shown by the unfamiliar tetrahedral environments of manganese( II ) and iron( II ) ions in complexation with the Schiff bases.
