The layers and their interactions with adjacent layers. In every case, the C—H⋯N interactions are shown with dashed lines. Top: layer 1, shown with solid bonds, and layer 1′, shown with dashed bonds, related to layer 1 by an inversion center at (, , 0). Center: layer 2, shown with solid bonds, and layer 1, shown with dashed bonds. Bottom: layer 3, shown with solid bonds, and layer 2, shown with dashed bonds. Note that the overlap 1–1′ is distinctly different from that of 2–1 and 3–2, which are similar to each other. |
