摘要：
Results of Mossbauer and EPR studies of univalent-iron monoazaetioporphyrin complexes [Fe(I)(MAEP)] are presented in this paper. Fe(I)(MAEP) were generated using the chemical reduction method. Three forms of the univalent-iron monoazaetioporphyrin complexes were observed: (1) typical Fe(I)(MAEP), (II) with an additional electron on the porphyrin ligand [Fe(I)(MAEP(.))](-) and (III) the Fe(I)(MAEPh) phlorin structure. Electron configuration of Fe(I) ions in these complexes is (d(xy))(2)(d(xz),d(yz))(4)(d(z)(2))(1). The [Fe(I)(MAEP(.))(-) structure is stable only in solution and it is transferred into Fe(l)(MAEP) in the solid state. Mossbauer parameters for all products of the reduction reaction are given.
