mu-nitrido diiron porphyrin complex (OEPFe)(2)N (OEP = octaethylporphyrinato dianion) was synthesized by the treatment of (OEPFe)Cl with hydrazoic acid followed by the thermal decomposition of formed (OEPFe)N-3 complex. The (OEPFe)(2)N complex was investigated by UV-vis, IR, HR ESI-TOF MS and EPR spectroscopic methods. EXAFS study indicated a very short Fe-Fe distance of 3.30 angstrom in this dimer compared with 3.48 angstrom distance between iron sites in the related mu-nitrido diiron complex on the tetraphenylporphyrin platform. This difference can be explained by the steric hindrance exerted by phenyl substituents in the latter. The spectral properties of the (OEPFe)(2)N complex are discussed. The catalytic properties of (OEPFe)(2)N were evaluated in the oxidation of cyclohexene and cyclohexane.
