Figure 5
Part of the crystal structure of (II), showing the formation of a hydrogen-bonded chain along [010]. The atom site denoted X1 is occupied by (0.5C + 0.5N) atoms (see Comment). For clarity, H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions ( − x, − + y, − z) and ( − x, + y, − z), respectively. |
