  text: <jats:p>The use of iron as a replacement for noble metals in photochemical
    and photophysical applications is challenging due to the typically fast deactivation
    of short-lived catalytically active states. Recent success of a cyclometalated
    iron(III) complex utilizing a bis-tridentate ligand motif inspired the use of
    phenyl-1H-pyrazole as a bidentate ligand. Five complexes using the tris(1-phenylpyrazolato-N,C2)iron(III)
    complex scaffold are presented. In addition to the parent complex, four derivatives
    with functionalization in the meta-position of the phenyl ring are thoroughly
    investigated by single crystal diffractometry, UV-Vis-spectroscopy, and cyclic
    voltammetry. Advanced X-ray spectroscopy in the form of X-ray absorption and emission
    spectroscopy allows unique insights into the electronic structure as well as DFT
    calculations. The ligand design leads to overlapping MLCT and LMCT absorption
    bands, and emissive behavior is suppressed by low-lying MC states.</jats:p>
