Figure 2
The molecular components of (II), showing the atom-labelling scheme for (a) isomer A, (b) isomer B, (c) isomer C and (d) an overlay of all three disorder components. In parts (a)–(c), displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. In part (d), atoms are drawn as spheres of arbitrary radii and the H atoms have all been omitted. This part is oriented to show the S configuration at atom C38, as opposed to the R configuration at atoms C8 and C58, and the locations of the methyl C atoms C111, C411 and C591. |
