Abstract: In the title dinuclear uranyl complex, (C(18)H(38)N(2)O(6))[(UO(2))(2)(NO(3))(4)(OH)(2)].H(2)O, each pair of uranyl ions in the two independent centrosymmetric dianionic dimers is bridged by the two hydroxide ions, with the nitrate ions ensuring equatorial hexagonal coordination. The dihydro[2.2.2]cryptand (4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane) dication presents an 'in-in' conformation (endo protonation) and it is hydrogen bonded to the hydroxide ions, either directly or via a water molecule, resulting in the formation of linear hydrogen-bonded polymers.
