Figure 1
The molecular structures of representative compounds selected to show the atom-labelling schemes and the different molecular conformations: (a) type 1 molecule in the 2-methylphenyl compound (II); (b) type 2 molecule in the 3-methylphenyl compound (III); (c) independent molecular components in the monohydrate of the 3-methoxyphenyl compound (XV); (d) molecule of the 2,6-difluorophenyl compound (XXI). In all cases the displacement ellipsoids are drawn at the 30% probability level. |
