Figure 2
Part of the crystal structure of (I), showing the formation of a hydrogen-bonded dimer. For clarity, H atoms bonded to C atoms that are not involved in the motif shown have been omitted, and only the major orientation of the disordered thiophene ring is shown. Hydrogen bonds are shown as dashed lines. The atom marked with an asterisk (*) is at the symmetry position (1 − x, 1 − y, 1 − z). |
