The title cobalt(II) complex was prepared by mixing equimolar amounts of {2,2′-[ethane-1,2-diylbis(nitrilo­methanylyl­idene)]diphenolato}cobalt(II) and N-ferrocenylisonicotinamide in dry di­chloro­methane under nitro­gen and subsequently characterized by ESI–MS, IR, and single-crystal X-ray diffraction. The structure at 100 K has triclinic (P ) symmetry and indicates that the complex crystallizes as a mixture of λ and δ conformers. It exhibits the expected square-pyramidal geometry about the CoII atom, and forms hydrogen-bonded dimers through the amide N—H group and one of the phenolate O atoms on adjacent mol­ecules.
