Abstract

A heterometal Cu₆Fe wheel molecule, [Cu^II₆Fe^III(HL)₆(OH)₂(OCH₃)₄](NO₃)₃·6H₂O (1·6H₂O) (H₂L = 1-(2-pyridine)-3-(2-pyrrole)acetylacetone) was synthesized by the one-pot reaction of H₂L with copper and iron sources. X-ray structural analysis reveals that the heptanuclear wheel cluster consists of a central Fe(III) ion surrounded by six Cu(II) ions, linked through methoxo- and hydroxo-bridges. Cryomagnetic studies indicate intramolecular antiferromagnetic interactions were operative.
