Figure 3
Part of the crystal structure of (I), showing the formation of hydrogen-bonded dimers linked to form a chain. Atoms marked with (i), (iii) or an asterisk (*) are at the symmetry positions (1 − x, 1 − y, −z), (1 − x, 2 − y, −z) and (x, 1 + y, z) respectively. Dashed lines indicate hydrogen bonds. |
