Depiction of the C—H⋯O hydrogen bonds (blue, dashed lines) present in the crystal of anhydride I, using a ball-and-stick model. For clarity, only those hydrogen atoms involved in an interaction are shown. Symmetry codes: (i) −x + 2, −y + 1, −z; (ii) x + 1, y, z; (iii) −x + 1, −y + 1, −z; (iv) −x + 1, −y + 2, −z; (v) x, y + 1, z. |
