Figure 2
Alternating A and B molecules of (I) stacked by π–π contacts along c. π–π contacts are shown as darker dashed lines (green in the electronic version of the paper), with the dark and light spheres (red and green, respectively) representing the centroids of the benzene rings of adjacent pairs of A and B molecules. C—H⋯O hydrogen bonds are shown as lighter dashed lines (turquoise). [Symmetry code: (iii) x, y, z − 1.] |
