Figure 4
Part of the crystal structure of (I), showing the formation of a hydrogen-bonded chain of R22(8) rings running parallel to the [10] 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 + ), (x + , −y + , z − ) and (−x + , −y + , −z + 1), respectively. |
