New iron complex studied by ESR spectroscopy

Here we present the synthesis and characterization of a new mononuclear iron(II) octahedral complex. Reaction of 2-hydroxy-6-methylpyridine (L) with iron(II) tetrafluoroborate results in the isolation of [FeL6](BF4)2. Polycrystalline sample of the complex has been investigated by X-band electron spin resonance (ESR) spectroscopy (microwave frequency ν ≈ 9.7 GHz). The measurements have been performed from room down to liquid helium temperature. The recorded spectra show very complex structure. The obtained results will be discussed in terms of the iron coordination and interaction between iron spins. The magneto-structural correlations will be established and comparison with similar compounds will be presented.
