Comparison of tetravalent cerium and terbium ions in a conserved, homoleptic imidophosphorane ligand field.

ABSTRACT: A redox pair of Ce⁴⁺ and Ce³⁺ complexes has been prepared that is stabilized by the [(NP(1,2-bis- ^t Bu-diamidoethane)(NEt₂))]^1- ligand. Since these complexes are isostructural to the recently reported isovalent terbium analogs, a detailed structural and spectroscopic comparative analysis was pursued via Voronoi-Dirichlet polyhedra analysis, UV-vis-NIR, L₃-edge X-ray absorption near edge spectroscopy (XANES), cyclic voltammetry, and natural transitions orbital (NTO) analysis and natural bond orbital (NBO) analysis. The electrochemical studies confirm previous theoretical studies of the redox properties of the related complex [K][Ce³⁺(NP(pip)₃)₄] (pip = piperidinyl), 1-Ce(PN)</
