The number of known high-oxidation-state transuranic compounds remains limited, and these typically feature high coordination numbers and/or multiply-bonded donor atoms. Now, a tetrahedral, pentavalent neptunium complex supported by four monoanionic ligands has been isolated and characterized. This complex is stable in the solid state and undergoes a proton-coupled electron transfer reaction in solution.
