Hydrochlorothiazide-1,4-dioxane(1/1)

Hydro­chloro­thia­zide forms a 1:1 solvate with 1,4-dioxane, C7H8ClN3O4S2·C4H8O2 [systematic name: 6-chloro-3,4-di­hydro-2H-1,2,4-benzothia­diazine-7-sulfonamide 1,1-dioxide–1,4-dioxane ({1/1})]. The asymmetric unit comprises one mol­ecule of hydro­chloro­thia­zide and halves of two solvent mol­ecules arranged around inversion centres. The structure contains a hydrogen-bonding network comprising three N—H⋯O and one N—H⋯N hydrogen bonds.
