Analysis of the properties of metallorganic compounds containing the Fe³⁺ nanoprobes

Abstract

Coordination compounds containing the Fe³⁺ ions like sodium salt Na[FeO₆(C₁₀H₈N)₃], kaolinite Al₂[Si₂O₅]⋅(OH)₄, metalloproteins (Ferritin, Maltofer, and Ferrum Lek) find a wide application. The analysis of the properties of these compounds has demonstrated a developed crystal structure. The diffractogram of Ferritin included an amorphous component. Within the temperature range of 4.2–300 К, all the compounds are characterized by transformation and mutual transfer of the lines of electron paramagnetic resonance spectrum of the Fe³⁺ ions (EPR). This fact allows estimation of a dynamical characteristic of the nearest neighbor environment of Fe³⁺.
