In the centrosymmetric formula unit of the title complex, C12H24O6.2C2H6OS.2C12H9F2NO4S2, each dimethyl sulfoxide molecule is bonded to 18-crown-6 via a set of C—HO interactions involving two H atoms of one methyl group. The sulfoxide O atoms accept a nearly linear N—HO hydrogen bond from the disulfonylamine NH functions [NO 2.651 (2) Å]. The macrocycle has approximately D3d symmetry, and the disulfonylamine molecules feature a folded pseudo-Cs symmetric conformation.
