title: Bis(pyridinium) trans-tetrachlorido-dioxidouranate(VI) dioxane solvate.
abstract: In the crystal structure of the title compound, (C(5)H(6)N)(2)[UCl(4)O(2)]·C(4)H(8)O(2), the pyridinium cations occupy general positions and the anions and the solvent dioxane mol-ecule are located on centres of inversion. The dioxane mol-ecules are connected to two symmetry-related pyridinium cations via O-H⋯O hydrogen bonding. There are additional inter-molecular C-H⋯Cl contacts, which are indicative of weak C-H⋯Cl inter-actions.
