In the title compound, C12H15O7PS, the P atom has a distorted tetrahedral environment. The P—O—C—C torsion angles deviate significantly from zero [average = 12.0 (3)°], indicating that the bicyclic OP(OCH2)3C cage is strained. In the crystal, weak C—H⋯O interactions consolidate the packing.

The title compound was obtained in the reaction of 4-(hydroxymethyl)-2,6,7-trioxa-1-phosphabicyclo[2.2.2]octane 1-oxide (5 mmol) and 4-toluenesulfonyl chloride(4.7 mmol) in refluxing acetonitrile (50 ml). The solvent was evaporated in vacuo. The title compound was recrystallized from ethanol and single crystals of (I) were obtained by slow evaporation.
All H atoms were placed in calculated positions, with C—H = 0.95 - 0.99 Å, and included in the final cycles of
using a riding model, with Uiso(H) = 1.2-1.5 Ueq(C).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. |

Caged bicyclic phosphates are widely used as flame retardants or pesticides (Li et al., 2000). They have been studied in the context of hydrogen-bond patterns (Guo & Zang, 2007). p-Toluenesulfonates are also used in monitoring the merging of lipids (Yachi et al., 1989), studying membrane fusion during acrosome reaction (Spungin et al., 1992). We report here the crystal structure of the title compound (I).
In (I) (Fig. 1), all bond lengths and angles are normal and correspond to those observed in the related compounds (Miu et al., 1991; Sheng & He, 2006; Guo & Zang, 2007). The P—O—C—C torsion angles deviate significantly from zero [averaged -12.0 (3)°] indicating that bicyclic OP(OCH2)3C cage is strained. In the crystal, weak C—H···O interactions (Table 1) consolidate the packing.
