Figure 5
Part of the crystal structure of (I), showing the hydrogen-bonded chain consisting of molecules A which runs parallel to [10]. Atoms labelled with an asterisk (*), hash symbol (#) or dollar sign ($) are at the symmetry positions (x − , −y + , z + ), (x + , −y + , z − ) and (x − 1, y, z + 1), respectively. Hydrogen bonds are shown as dashed lines and uninvolved H atoms have been omitted. |
