Figure 3
Part of the crystal structure of (I), showing the formation of the (100) chains via hydrogen bonds and π–π stacking interactions. Labels Cg represent the centroids of rings A and C. Atoms marked with an asterisk (*), hash (#) or ampersand (&) are at the symmetry positions (1 − x, y, z), ( − x, + y, − z) and (1 + x, y, z), respectively. For clarity, some H atoms have been omitted. |
