A comparison of the observed conformers for the title compound, viewed down the Cl—Sn—O axis (top: the previously known polymorph; bottom: the new P21 polymorph). Note the different orientations observed for the apical DMSO molecule. The calculated powder patterns displayed on the right show that both polymorphs are crystallographically very different. Patterns were calculated with Mercury (Macrae et al., 2008; 5 < 2θ < 40°, λ = 1.54056 Å, FWHM = 0.2°). |
