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.
