Figure 1
The structure of (I), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as spheres of arbitrary size. DMSO molecules and aromatic H atoms have been omitted for clarity. Atoms without labels or marked with a superscript `i' are at the symmetry position (2 − x, 1 − y, 2 − z). |
