Figure 2 The crystal structure showing the formation of the centrosymmetric (8) dimer for both the molecules. For the sake of clarity, the H atoms not involved in the motif have been omitted. The atoms marked with an asterisk (*) are at the symmetry positions (1 − x, 1 − y, 1 − z) and (1 − x, −y, −z). The dashed lines indicate hydrogen bonds. |
