Figure 5
Molecular structures and atom-labelling scheme of the asymmetric units of (1)-(4), showing super-positions of the two molecules in the solid solution. Displacement ellipsoids are shown at the 50% probability level. See Table 1[link] for the relative site occupancies of each molecule. Note the trans conformations of the amide and thioamide moieties in all of the solid solutions.  [article HTML]
