Zusammenfassung

The synthesis and characterization of complex [Fe{(SePPh₂)₂N}₂] (1) is described. X-ray crystallography shows that this system contains a tetrahedral FeSe₄ coordination sphere. The structural features of 1 are compared with those of similar first row transition element complexes, including a recently reported preparation of [Fe{(SePPh₂)₂N}₂] (1_SP) exhibiting a highly unusual square planar FeSe₄ coordination sphere. The electronic structure of 1 was elucidated by magnetometry, high-frequency EPR, and Mössbauer spectroscopic studies, which reveal zero-field splitting (ZFS) parameters typical of high spin S = 2 tetrahedral Fe^II sites. Accurate ZFS parameters (D = +8.22 cm^–1, E/D = 0.104) were obtained by analysis of the EPR spectra and compared with those of the analogous [Fe{(SePPh₂)₂N}₂] complex.
