The data collection sample was selected directly from many nicely formed specimens found in the bottle from the manufacturer.
A Fourier map around the expected positions of the methyl group H atoms clearly indicated two equivalent orientations. Both sets were included (riding model) and their occupancies refined, although the refined value is indistinguishable from 0.50. The C—H distance and C—C—H angles for the methyl H atoms were fixed, but the groups were allowed to rotate around the C—C bond.
3-chloro-2-methylbenzenesulfyl derivatives have shown biological activity as hydroxysteroid dehydrogenase inhibitors. These derivatives have potential as medicants to treat diseases mediated by hydroxysteroid dehydrogenase, such as type-2 diabetes (Brennan et al., 2006).

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. |
