Bis­(methyl­sulfon­amido) sulfone, C2H8N2O6S3 or SO2(NHSO2CH3)2, was synthesized from imidobis­(sulfonyl ­chloride), HN(SO2Cl)2, and bis­(tri­methyl­silyl)­methane, CH2[Si(CH3)3]2, in ­chlorotri­methyl­silane solution. In the solid state, there are two independent mol­ecules linked by two N—H⋯O hydrogen bridges into infinite chains parallel to the b axis. The central S atoms of the independent molecules each lie on a twofold axis. Bis­(tri­fluoro­methyl­sulf­onamido) sulfone, C2H2F6N2O6S3 or SO2(NHSO2CF3)2, was formed by the reaction of tri­chloro­phosphazosulfuryl tri­fluoro­methane, Cl3PNSO2CF3, with fluoro­sulfonic acid, FSO3H. The mol­ecules are connected by bifurcated N—H⋯O bridges into infinite layers parallel to the [001] plane. The central S atom lies on a twofold axis.
