- 요약The lanthanides were traditionally observed primarily in the 3+ oxidation state, particularly under ambient/aqueous conditions. In 2019 our research group introduced one of the first examples of Tb4+ in a molecular complex, complete with thorough magnetic and physical characterization. Extending this method to Pr4+resulted in a fleeting complex which was thermally unstable and only characterizable in solution. Due to these restraints, the full characterization of its physical properties was not achievable.Chapter 1 consists of an introduction to the field of high-valent lanthanide chemistry, including earlier examples from our research group. To understand the factors that modulate the potential of the lanthanide 3+/4+ redox couple in imidophosphorane complexes, a complete alkali metal series was synthesized and rigorously studied (Chapter 2). To address the stability of Pr4+ in an imidophosphorane ligand framework, the reported [NPtBu3] 1- ligand was employed, resulting in a thermally robust Pr4+ imidophosphorane complex (Chapter 3). In addition to structural characterization, the Pr4+ complex was magnetically characterized and crystal field effects compared to the isoelectronic Ce3+congener were evaluated.In addition to imidophosphorane frameworks, the utility of an anionic phosphoramide ligand was explored. The synthesis of the novel phosphoramide ligand, as well as a broad variety of coordination chemistry at diamagnetic La3+ is detailed (Chapter 4). Overall, significant advancements in non-aqueous tetravalent lanthanide chemistry are covered, and the thorough characterization of Pr4+in a molecular complex is reported.
