Figure 5
(a) One layer of bianthrone molecules viewed along the b axis. C13H8⋯O1 contacts are shown as dashed lines. (b) Layers of bianthrone viewed along a. (c) Layers of bianthrone viewed along c. (d) The strongest intermolecular interactions in bianthrone shown as solid black lines (35 kJ mol−1) or black dashed lines (10–18 kJ mol−1). Superimposed on the diagrams (a) and (d) are the principal axes of the strain tensor. The largest component is in red, the smallest blue and the middle in orange. Notice that the largest component avoids the strongest contacts. The red labels #1–#5 represent the PIXEL interactions in Table 2[link]. The molecules involved in interactions #1 and #3 are related by a lattice translation along a, and are superimposed in the projection shown in (b), but can be more clearly distinguished in (c).
