Figure 2
The two independent molecules in the selected asymmetric unit for compound (II), showing the atom-labelling scheme, viz. (a) the 2R,3S,5R,6S enantiomer of molecule 1 and (b) the 2S,3R,5S,6R enantiomer of molecule 2. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. |
