Figure 5
(a), (b) Pairwise stacking interactions in crystals of (1) and (4) involving both naphthalimide rings present in a molecule, (c) semi-transparent surface of (3) showing the area engaged in pairwise stacking interactions. At the far right of (c) the indentations on the surface reflect intermolecular C—H⋯π interactions shown in Fig. 4[link](b), which involve the naphthalimide ring not engaged in stacking.
