Details of the intermolecular interactions in the crystal of (I), showing (a) π–π stacking between rings 1 (N1/N2/C13–C16) and 2 (C1–C6) along the [010] direction, (b) an inversion dimer formed by the C9—H9C⋯O7ii hydrogen bond and (c) by the C8—H8B⋯O6i hydrogen bond. [Symmetry codes: (i) x, y, 1 + z; (ii) −1 − x, 1 − y, −z.] |
