Hirshfeld surfaces [front (top) and back (bottom) views] for compounds (I)–(VI) mapped over dnorm and shape index. Each surface is viewed approximately perpendicular to the molecular plane. The π–π interactions are shown by white circles, and the Cl⋯Cl contacts, the C—H⋯O, C—H⋯Cl, N—O⋯π and C—H⋯π interactions are indicated by green, black, green cyan, magenta and violet arrows, respectively. |
