Figure 1 The molecular structure and atom numbering scheme of the heterodimer of (1R,6R)-1-methyl-8-azaspiro[5.6]dodecan-7-one. The respective methyl group (C13) adopts an axial or equatorial position on its associated cyclohexane ring as shown. Ellipsoids are drawn at the 50% probability level. H atoms are represented as small spheres of arbitrary radii. Hydrogen bonds are shown as dashed lines. |
