Figure 6
Part of the crystal structure of (II), showing the formation of a hydrogen-bonded chain along [10]. The atom site denoted Y1 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. |
