[NBnMe3]2[Fe2Cu4(SePri)8Cl2] and [NBnMe3]2[Fe3Cu(SePri)6Cl3], novel heterometallic chalcogenolate complexes with dodecahedral and octahedral selenium cages

Abstract

[Fe₂Cu₄(SePrⁱ)₈Cl₂]^2–, an unprecedented hexanuclear mixed iron–copper–selenolate cage complex containing a dodecahedral selenium framework and [Fe₃Cu(SePrⁱ)₆Cl₃]^2–, a related tetranuclear complex anion with an octahedral selenium arrangement, are described.
