English[NaFe6(OMe)12(dbm)6]Cl·12MeOH·CHCl3 (I; dbmH = dibenzoylmethane) was prepd. and characterized by elemental anal., spectral (UV, IR), x-ray crystallog., and magnetic methods. The 6 Fe atoms are located at the vertexes of an almost regular hexagon, with Fe···Fe sepns. in the range 3.18-3.20 Å and vertex angles of 119.5-120.5°. The ring serves as a host for the Na ion. Antiferromagnetic exchange coupling interactions exist between the paramagnetic Fe(III) centers (J = 20 cm-1). I is a good structural model for cyclic intermediates proposed for the polyalc.-promoted hydrolysis of Fe(III) salts.
