A Comparative Study of Nitrate and Iodide of the Spin-Variable Iron(III) Cation with the N4O2 Coordination Sphere by Mössbauer Spectroscopy

The spin state of the magnetic center for a spin-variable cation with nitrate [Fe III (3-OMe-Sal 2 trien)]NO 3 ⋅H 2 O( I ) and iodide [Fe III (3-OMe-Sal 2 trien)]I ( II ) anions is studied by Mössbauer spectroscopy on 57 Fe nuclei (3-OMe-Sal 2 trien is the condensation product of triethylenetetramin...

Description
Summary:The spin state of the magnetic center for a spin-variable cation with nitrate [Fe III (3-OMe-Sal 2 trien)]NO 3 ⋅H 2 O( I ) and iodide [Fe III (3-OMe-Sal 2 trien)]I ( II ) anions is studied by Mössbauer spectroscopy on 57 Fe nuclei (3-OMe-Sal 2 trien is the condensation product of triethylenetetramine with 3-methoxy salicylaldehyde) in the temperature ranges of 5 to 305 and 85 to 296 K, respectively. It was shown that, for both complexes, only one low-spin ( S = 1/2) doublet from iron(III) ions appears in the spectra, despite significant differences (up to ~10%) in the length of the iron(III)–ligand bonds in the N 4 O 2 coordination octahedron of the salt II compared with I , according to X-ray diffraction data at 293 K. The Debye temperatures were determined for both compounds, Θ = 157 and 153 K.
