Detail of the intermolecular C—H⋯O hydrogen bonds (black dashed lines) and π–π-stacking interactions (orange dashed lines) [symmetry codes: (i) −x + 1, y − , −z + ; (ii) −x + 1, y + , −z + ; (iii) x, −y + , z − ; (iv) x − 1, −y + , z − ; Cg2, Cg3 and Cg4 are the centroids of the C1/C6/C7/N1/N2, C1–C6 and C12–C17 rings, respectively]. |
