Figure 3 The crystal structure of the title compound. Neighbouring sheets are connected by a pair of C—H⋯π hydrogen bonds (dashed lines). For clarity, H atoms not involved in the hydrogen bonding have been omitted. [Symmetry code: (A) ( − x, − + y, − z, (B) − + x, − y, + z, (C) 1 − x, 1 − y, 1 − z]. |
