Figure 1 Asymmetric unit in the crystal structure of (I). Displacement ellipsoids for non-H atoms are drawn at the 50% probability level. Cyan dashed lines indicate weak hydrogen bonds. [Symmetry codes: (i) x, y, 1 + z; (ii) x, 1 + y, z; (iii) − x, + y, −z; (iv) x, y, −1 + z; (v) − x, − + y, −z; (vi) x, −1 + y, z.] |
