Figure 3 Part of the crystal structure of (I) showing the formation of a sheet of (8) and (14) centrosymmetric rings parallel to (100) generated by the C—H⋯O hydrogen bonds. Symmetry codes: (i) x, y, 1 − z; (ii) −x, −y, −z; (iii) −x, −y, 1 − z; (iv) x, y, 1 + z; (v) −x, −y, 2 − z. For the sake of clarity, the H atoms not involved in the motif have been omitted. |
