Figure 3
The weak nonbonding intermolecular interactions in (1). Dashed lines indicate the intermolecular C—H⋯π and terminal benzene C—H⋯O=C interactions in part (a) and the internal benzene C—H⋯O=C interactions in part (b). As described in the text, all contact distances are longer than the sum of the van der Waals radii. See Table 2 for symmetry codes. |
