Opis:: Results of Mössbauer 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: (I) 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 (dxy)2(dxz ,dyz)4(dz 2)1. The [Fe(I)(MAEP•)]- structure is stable only in solution and it is transferred into Fe(I)(MAEP) in the solid state. Mössbauer parameters for all products of the reduction reaction are given.

Opis:: Results of Mössbauer and EPR study of a univalent-iron phthalocyanine complex (FeIPc) are presented in this paper. FeIPc has been obtained from FeIIPc by the chemical reduction method in tetrahydrofuran (THF) and dimethoxyethan (DME) solutions. Like in the case of FeI-porphyrin complexes, Mössbauer and EPR data as well as quantum calculations of electronic absorption spectra confirm in this case a low-spin configuration of FeI ions with an unpaired electron located at dz2 orbital. Interaction between FeIPc and THF molecules does not change significantly the electron configuration of FeI ions coordinated to phthalocyanine ligand.
