Centroid–centroid distances between nearby pyridyls in 1 viewed down the b axis illustrated using Mercury (Macrae et al., 2020). Hydrogen atoms are omitted for clarity. Ring centroids are shown as red spheres. For additional numerical data, see Table 2. Symmetry codes: (i) 1 − x, + y, − z; (ii) 1 − x, 1 − y, 1 − z; (iii) 1 − x, − + y, − z; (iv) 2 − x, 1 − y, 1 − z. |
