Figure 3
Part of the crystal structure of (IV), showing the formation of the hydrogen-bonded chain along [010]. For the sake of clarity, H atoms bonded to C atoms have been omitted, and only one orientation of the disordered nitro group is shown. Atoms marked with an asterisk (*), hash (#) or dollar sign ($) are at the symmetry positions ( − x, + y, − z), (x, 1 + y, z) and ( − x, y − , − z), respectively. |
