Coordination of trivalent lanthanum and cerium, and tetravalent cerium and actinides (An = Th(iv), U(iv), Np(iv)) by a 4-phosphoryl 1H-pyrazol-5-olate ligand in solution and the solid state

Abstract

Single crystal X-ray analyses, solution NMR and EXAFS studies of a series of f-elements metal(iv) complexes of a 4-phosphoryl pyrazolone ligand show essentially the same coordination of the metal ions in solution and in the solid state.
