Figure 5 Part of the crystal structure, showing the aggregation of (4) (10) and (6) motifs via N—H⋯O hydrogen bonds. Atoms marked with an ampersand (&), an at sign (@), a hash symbol (#), dollar sign ($), percent sign (%), or a star sign (*) are at the symmetry positions (1 − x, 1 − y, 1 − z), (−1 + x, y, z), (1 − x, y, 1 − z), (−x, −y, 1 − z), (1 + x, y, z), (2 − x, 1 − y, 1 − z), respectively. |
