Figure 7
A view of the Hirshfeld surface mapped over dnorm (left) and fingerprint plot (right) for 1. The highlighted red spots on the top face of the surfaces indicate contact points with the atoms participating in the C—H⋯O intermolecular interactions whereas those on the middle of the surface correspond to C⋯C contacts consequent of the π–π stacking. The C⋯C contacts contribute to higher the frequency of the pixels at de ≃ di ≃ 1.8 Å on the FP plots (yellow spot). |
