Abstract
Iron(II) dicyanamide and isothiocyanate compounds with 2-(2- tert -butyltetrazol-5-yl)pyridine (L) of the composition [FeL2(C2N3)2]×2H2O (I) and [FeL2(NCS)2]H2O (II) are synthesized and studied. The compounds are examined using powder and single crystal XRD (for I), electron (diffuse reflectance spectra) and IR spectroscopy, static magnetic susceptibility. The analysis of the dependence meff( Т ) indicates that the exchange interactions of antiferromagnetic nature appear between the iron(II) ions at temperatures below 50 K.
