Figure 2 A larger portion of the crystal structure of (I), showing the formation of a hydrogen-bonded chain built from C—H⋯O. For clarity, H atoms not involved in the hydrogen bonding have been omitted. Dashed lines indicate hydrogen bonds [symmetry codes: (A) 2 − x, 2 − y, z; (B) 3 − x, 2 − y, 2, z; (C) −1 + x, y, z]. |
