A packing diagram for title compound showing the π–π stacking interactions (dashed lines). H atoms not involved in hydrogen bonding have been omitted for clarity. Cg1 and Cg2 are the centroids of the pyrozolone and C13–C18 rings, respectively. [Symmetry codes: (ii) 1 − x, 1 − y, 1 − z; (iii) + x, − y, + z.] |
