Figure 7
Packing diagrams of filled unit-cell contents of (a) (1), (b) (2), (c) (3) and (d) (4). Noteworthy are the isostructural structures of (a)-(c), illustrating F, Cl and methyl exchange in N-phenylformamides and N-phenylthioamides. The outlier is (4), which crystallizes in a different space group with different unit-cell parameters.  [article HTML]
