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.
