X-ray and 57Fe Mössbauer study on a Fe(III) complex of 2-acetyl-1,3-indandione

Single-crystal X-ray structure of an iron(III) complex of 2-acetyl-1,3-indandione is resolved which reveals that a racemic mixture, composed of Δ-fac and Λ-fac stereoisomers, is formed. Both species have octahedral geometry, but slightly distinguishable. Detailed Mössbauer data indicate a high-spin electronic structure of the Fe(III) centres Fe1 and Fe2 with spin–spin magnetic relaxation process. Two different approaches for computer processing of the experimental Mössbauer spectra are considered.
