Figure 4
Stereoview of parts of the crystal structure of (V) and (XV) showing (a) the sheet parallel to (100) in (V) built from two C—H⋯π(arene) hydrogen bonds, and (b) the sheet parallel to (100) in (XV) built from C—H⋯N and C—H⋯π(pyridyl) hydrogen bonds. For the sake of clarity, the H atoms not involved in the motifs shown have been omitted. |
