Figure 3 Part of the crystal structure of (I) , showing the linkage of adjacent 2-D layers by C9-H9A⋯O5, C10-H10A⋯O4 hydrogen bonds and π-π stacking interactions, which form the three-dimensional network. The green outlined area shows the 2-D layer parallel to the (001) plane. For the sake of clarity, H atoms not involved in the motifs have been omitted. |
