Single-Determinant Ground State in Ce⁴⁺ Imidophosphorane Complexes.

ABSTRACT: X-ray spectroscopy techniques are critical in the electronic structure analysis of high-valent lanthanides. The interpretation of multipeaked features at the lanthanide L₃-edge has remained a challenging question, as it is observed across a range of material classes. A series of structurally related Ce⁴⁺complexes were prepared to probe the potential ligand field perturbation of the ground state within the series. The tuning of relative 4f and ligand orbital energies in homoleptic and heteroleptic tetravalent Ce imidophosphorane complexes is achieved through ligand derivatization and is clearly demonstrated by UV-vis spectroscopy and electrochemically measured redox potentials. However, Ce L₃-edge high-energy resolution fluorescence-dete
