Magnetic Properties Variations in Iron Complexes with Benzimidazole Derivatives Depending on the System Spin State
Keyword(s):
Complexes of bivalent and trivalent iron with ligands based on benzimidazole derivatives have been synthesized and investigated. Chloride-ion was used as anion. Samples ligands differed from each other in the length of alkyl radical. Some samples were found in a mix-valence state, that complicated spin transition observation. Combination of Mossbauer spectroscopy and magnetic moment in high field (15kOe) measurements in the temperatures range 130K - 350K allowed us to establish the valence of iron ions under spin transition in our samples and spin transition temperature frameworks for these mix-valence compounds.
