The title compound, bis(propane‐1,2‐diaminium) tetraaquadi‐μ 2 ‐sulfato‐disulfatotetraoxodiuranate(VI) dihydrate, (C 3 H 12 N 2 ) 2 [U 2 O 4 (SO 4 ) 4 (H 2 O) 4 ]·2H 2 O, contains discrete centrosymmetric anionic {[UO 2 (H 2 O) 2 (SO 4 ) 2 ] 2 } 4− dimers with C 3 H 12 N 2 2+ cations balancing the charge. The dimers form hydrogen‐bonded layers. The cations and occluded water molecules participate in an extensive hydrogen‐bonding network. Each U VI centre is seven‐coordinate with a pentagonal–bipyramidal geometry. Both pendent and bridging sulfate tetrahedra are observed, as well as bound and occluded water molecules.
