Bis(propan-2-yl) [(1S)-1-(4-fluoro-phen-yl)-1-hydr-oxy-2-nitro-ethyl]phospho-nate

Abstract

In the title compound, C(14)H(21)FNO(6)P, a staggered conformation about the central P-C bond occurs, with the oxo and hydroxyl groups occupying diagonally opposite positions. The crystal structure features supra-molecular chains mediated by O-H⋯O hydrogen bonds, which propagate in the a-axis direction. A C-H⋯O inter-action consolidates the chains. Disorder was resolved for one of the isopropyl groups with a 0.60 (2):0.40 (2) occupancy ratio for the two components.
