The singular Pu IV hexanuclear cluster [Pu 6 (OH) 4 O 4 ] 12+ stabilized by 1,4,7,10‐tetraazacyclododecane‐1,4,7,10‐tetraacetic acid (DOTA) ligands was structurally characterized for the first time both in the solid state and in water solution by using X‐ray diffraction and X‐ray absorption and UV/Vis spectroscopy. The stability of this cluster in water and its high solubility over a large pH range are of upmost importance for plutonium environmental speciation with potential applications in a related migration model.
