Abstract: The title compound, Cs3[PuO4(OH)2]·3H2O, contains centrosymmetric [PuO4(OH)2]3- anions. The Pu atom in this anion has an almost ideal tetragonal bipyramidal oxygen environment. The Pu-O distances are 1.8889 (14) and 1.8685 (15) Å in the PuO4 group and 2.3726 (15) Å to the OH groups. In the isostructural NpVII compound, Cs3[NpO4(OH)2]·3H2O, the Np-O distances in the NpO4 group are nearly the same as the Pu-O distances here, but the distances to the OH groups are about 0.04 Å longer.
