Figure 4
Part of the crystal structure of (I)[link], showing the formation of a hydrogen-bonded chain of R22(8) rings running parallel to the [10[\overline{1}]] direction. For the sake of clarity, H atoms bonded to C atoms have been omitted. Dashed lines indicate hydrogen bonds. Atoms marked with an asterisk (*), a hash symbol (#) or a dollar sign ($) are at the symmetry positions (−x + 1, y, −z + [{1\over 2}]), (x + [{1\over 2}], −y + [{1\over 2}], z − [{1\over 2}]) and (−x + [{1\over 2}], −y + [{1\over 2}], −z + 1), respectively.
