dc.description.abstractengThis PhD thesis focuses on the development and characterization of new organometallic iron complexes as models for abundant enzymatic systems. The use of a macrocyclic tetracarbene ligand system results in novel features of the organometallic iron complexes compared to literature-known nitrogen-coordinated model compounds. In particular, the strong σ-donating carbene donors induce a destabilization of the d(x²−y²) orbital and thus an increased HOMO−LUMO gap in the oxoiron(IV) complex studied in this thesis. This makes the high-valent oxoiron(IV) compound a unique system which is able to activate weak C–H bonds via the triplet pathway only. Moreover, mixed-valent and high-valent µ-nitridodiiron systems are developed and their properties are studied by a series of analytical techniques including x-ray diffraction and Mössbauer spectroscopy. Furthermore, a complete series of structurally characterized {FeNO}6–8 species is presented. Using a variety of spectroscopic and theoretical methods, the redox processes within this series are identified as largely metal centered. Finally, initial studies toward the development of new hybrid ligand systems combining N-donating and C-donating groups are described.de
