Ferrocene carboxamide, FcCONH2, forms homo- and heteroleptic complexes with Co(II), Ni(II) and Cu(II) via coordination of its carbonyl group. Whereas for both Co(II) and Ni(II), hexaferrocenyl complexes are obtained in the presence of BF4− anion, in the case of Cu(II) a tetraferrocenyl species is observed in the presence of triflate anion.
