Figure 2
Part of the crystal structure of (I), showing the formation of a cyclic centrosymmetric dimer built from paired C—H⋯O hydrogen bonds. For the sake of clarity, H atoms bonded to C atoms but not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) are at the symmetry position (1 − x, 2 − y, 1 − z). |
