Arranging up to six ferrocene carboxamides around metal centres

摘要

Ferrocene carboxamide, FcCONH(2), 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.
