Figure 4
Stereoviews of parts of the crystal structure of the 3-fluorophenyl compound (III) showing (a) the formation of a C₂²(7) chain along [100] built from N—H⋯O and N—H⋯N hydrogen bonds, and (b) the formation of an R₈⁸(64) sheet parallel to (101) built from N—H⋯O and C—H⋯N hydrogen bonds. For the sake of clarity, the minor orientation of the disordered type 2 molecule and the H atoms not involved in the motifs shown have been omitted.
