Abstract

The title complex, [Fe2(C18H18N4)2O(SO4)](ClO4)2·0.75C2H3N·0.25H2O, consists of two perchlorate ions, a solvent cavity with acetonitrile and water (disordered 3/1), and an Fe complex dication. The dication is a diiron(III) unit containing an oxo bridge and a sulfato bridge. The iron(III) centers are pseudo‐octahedral, six‐coordinate, with tris(2‐pyridylmethyl) amine (TPA) providing four N atoms. The distances and angles are typical for bent μ‐oxo‐bridged TPA complexes. The complex was the unexpected result of a reaction designed to produce a μ‐sulfido–μ‐carboxylato–diiron center.
