Figure 7
Hirshfeld short contact (d_norm) plots of m′CNpCH₃ (left) and m′BrpCH₃ (right) showing the C17—H17A⋯N1 and C16—H16A⋯Br1 (top), as well as C7—H7⋯N1, C7—H7⋯Br1, and C6—Br1⋯Br1 (bottom) interactions. Red, white, and blue surface colors indicate contacts less than the sum of the van der Waals radii, equal to, or greater than, respectively. Note that the C7—H7⋯N1 interaction for m′CNpCH₃ involves three molecules, while for m′BrpCH₃ both C7—H7⋯Br1 and Br⋯Br1 interactions are needed to support a similar three-molecule arrangement.
