The packing of the molecules of (I) in the crystal structure. The pairs of molecules formed by the C—H⋯O hydrogen bonds (long-dashed lines) and π–π interactions (short-dashed lines) form ribbon-like chains running along the c axis. [Symmetry codes: (i) −x, −y + 1, −z; (ii) −x, −y + 1, −z + 1; (iii) −x + 1, −y + 1, −z + 1; (iv) x + 1, y, z.] |
