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

Abstract

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 thecaxis.
