Details of the hydrogen bonding [N—H⋯N hydrogen bonds are represented by blue dashed lines and C—H⋯π(ring) interactions are represented by purple dashed lines] and π–π stacking interactions (orange dashed lines). Cg1–Cg4 are the centroids of the N1/C1/C6/N2/C9, N2/C9/N3/C8/C7, C1–C6 and C11–C16 rings, respectively. [Symmetry codes: (i) 1 − x, 1 − y, 1 − z; (ii) 1 − x, 1 − y, −z; (iii) x, −1 + y, z; (iv) −1 + x, y, 1 + z.] |
