Figure 2 The arrangement of molecules A (solid line) and B (solid open line), showing the intermolecular N—H⋯N and C—H⋯O hydrogen bonds (dashed lines) and also the aromatic π-π stacking interactions (double dashed lines). Dotted lines indicate intramolecular hydrogen bonds. The atoms of disordered part C (with the smaller occupancy factor) and H atoms not involved in hydrogen bonding have been omitted for clarity. |
