In the centrosymmetric formula unit of the title complex, C8H16O4.2C12H11NO4S2, the disulfonylamine molecules are linked to 12-crown-4 via a slightly bent N—HO hydrogen bond [NO 2.771 (2) Å]. The macrocycle adopts the [66] conformation and the (PhSO2)2NH molecules have an open pseudo-C2 symmetric conformation with the phenyl groups lying on opposite sides of the S—N—S plane.
