文摘

The tetrapodal pentaamine 2,6-C₅H₃N[CMe(CH₂NH₂)₂]₂ (pyN₄, 1), which possesses four equivalent primary amino groups, has been used to prepare the diiron(III) oxo complex [(1)₂Fe₂(μ₂-O)](ClO₄)₄(2), by aerobic oxidation of the mononuclear iron(II) aqua complex in methanol. This synthesis is unusual because iron(II) complexes of primary amines are normally unstable with respect to metal-induced ligand oxidation. X-ray as well as Mössbauer data indicate a high-spin electronic configuration for the metal centres in the dinuclear complex.
