In the title compound, C14H21FNO6P, a about the central P—C bond occurs, with the oxo and hydroxyl groups occupying diagonally opposite positions. The features supramolecular chains mediated by O—H⋯O hydrogen bonds, which propagate in the a-axis direction. A C—H⋯O interaction 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.

The C-bound H atoms were geometrically placed (C—H = 0.95–1.00 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C). The methyl H-atoms were rotated to fit the electron density. The O–H H atom was located from a difference map and refined with O–H = 0.840±0.001 Å, and with Uiso(H) = 1.5Ueq(O). Disorder is evident in the structure as seen in the anisotropic displacement parameters associated with several residues. However, multiple sites were only resolved for the C6 atom. Two distinct sites were resolved from isotropic
of C6/C60 with the major component having a site occupancy factor of 0.60 (2).Data collection: CrystalClear (Rigaku/MSC, 2005); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

In connection with previous studies on the enantioselective nitroaldol reaction of α-ketophosphonates and nitromethane for the synthesis of optically active α-hydroxy-β-nitrophosphonates, the title compound, (I), was investigated. The crystal structure analysis of (I), Fig. 1, shows an S-configuration about the C7 atom. When viewed down the P–C7 axis, the molecule has a staggered conformation with the P═O and OH groups being diagonally opposite. The presence of O–H···O hydrogen bonding formed between the hydroxyl-O4—H and O═P atoms leads to the formation of supramolecular chains along [1 0 0], Fig. 2 and Table 1. Stability to these chains of linear topology is afforded by C–H···O contacts, Table 1.
