Abstract
In the title compound, C13H18O3SSi, the SO3 group displays a partial rotational (ca 50°) disorder about the C—S bond, with relative proportions 0.7744 (13):0.2256 (13). This disorder also forces the propynyl CH2 group to be disordered.

Summary
Key indicators: single-crystal X-ray study; T = 90 K, P = 0.0 kPa; mean (C–C) = 0.003 A; disorder in main residue; R factor = 0.045; wR factor = 0.108; data-toparameter ratio = 26.7. C13H18O3SSi, the SO3 group displays a partial rotational (ca 50) disorder about the C—S bond, with relative proportions 0.7744 (13):0.2256 (13). This disorder forces the propynyl CH2 group to be disordered. Related literature For information on the title compound, see: Westmijze & Vermeer (1979); Tanabe et al (1995); Morales (1995)
