Abstract

Crystal and molecular structure of methyl 2-bis(pentyloxy)phosphoryl-2-phenylsulfonamido-3,3,3-trifluoropropionate (I) was determined by XRD analysis: space group\(P\bar 1\), a=9.406(3), b=12.068(6), c=14.150(8) Å, α=66.88(5), β=68.61(5), γ=71.33(5)°, Z=2, R=0.090 (CAD-4 automatic diffractometer, λCuKα, 1950 independent reflections with I≥2σ). The S and P atoms of molecule I have a distorted tetrahedral coordination. The S−N−C−P torsion angle is 159.4°. The two pentyl substituents in structure I have different conformations, and their atoms make rather intense thermal vibrations. In crystal structure I, the molecules are linked into centrosymmetric H-dimers by pairs of intermolecular hydrogen bonds N−H...O=P.
