Figure 2
A packing diagram of (I), showing the ribbon structure running along the b-axis direction formed via the N—H⋯O and C—H⋯O hydrogen bonds (green dashed lines) and π–π interactions (magenta dashed lines). H atoms not involved in the hydrogen bonds are omitted for clarity. Cg2 and Cg3 are the centroids of the N2/C8–C11/C16 and C11–C16 rings, respectively. [Symmetry codes: (vi) −x + 1, −y + 2, −z + 1; (vii) x, y − 1, z.] |
