Tetra­methyl­ammonium dimethyl (phenyl­sulfonyl­amido)phosphate(1-)

The title compound, C₄H₁₂N⁺·C₈H₁₁NO₅PS^-, was obtained from tetra­methyl­ammonium hydroxide and dimeth­yl(phenyl­sulfon­yl)amido­phosphate. The tetra­methyl­ammonium cation has a slightly distorted tetra­hedral configuration and the N-C bond lengths lie in the range 1.457 (3)-1.492 (3) Å. In the crystal, no classical hydrogen bonds are observed between the cation and the anion.

Tetra­methyl N,N′-(2,2,3,3,4,4-hexa­fluoro-1,5-dioxopentane-1,5-di­yl)bis­(phospho­ramidate)

The mol­ecule of the title compound, C₉H₁₄F₆N₂O₈P₂, lies on a twofold rotation axis that passes through the middle C atom of the three-atom fluoro­methyl­ene unit. The carbonyl and phosphoryl groups are in an antiperiplanar conformation. In the crystal, N—H...O=P hydrogen bonds link the mol­ecules into polymeric chains parallel to the c axis.
