Figure 4
The two enantiomers of the anion in (II). The bonds in the major enantiomer [occupancy 0.745 (8)] are shown as full lines and the bonds unique to the minor enantiomer [occupancy 0.255 (8)] are shown as dashed lines (see text). Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. |
