Structural and electrochemical characterization of a cerium(iv) hydroxamate complex: implications for the beneficiation of light rare earth ores

Abstract

Reaction of N-phenyl-pivalohydroxamic acid with CeIII precursors leads to a homoleptic hydroxamate complex: CeIV[tBuC(O)N(O)Ph]4. Electrochemical experiments indicate a significant stabilization of the CeIV cation at Ep,c = −1.20 V versus SCE in the hydroxamate ligand framework. The spontaneous oxidation of CeIII in a hydroxamate ligand field is discussed in the context of beneficiation of the light rare earths from the fluorocarbonate mineral bastnäsite.
