    ABSTRACT: The title compound, C(24)H(20)Br(2)N(2)O(4), is an 18-membered tricycle including two isoxazole rings. The asymmetric unit contains one half of the formula unit; a centre of inversion is located at the centroid of the compound. The dihedral angle between adjacent isoxazole and benzene rings is 84.0 (2)°. The compound displays intra- and inter-molecular π-π stacking inter-actions between the isoxazole rings, the shortest centroid-centroid distances being 3.837 (3) and 3.634 (3) Å, respectively. The mol-ecules are stacked in columns along the a axis with short Br⋯Br contacts [3.508 (1) Å].

    ABSTRACT: The title compound, C(29)H(29)NO(3), the nearly planar nine-membered indanedione ring [maximum deviation = 0.027 (2) Å] is located approximately parallel to its carrier pyridine ring [maximum deviation = 0.021 (2) Å] with a dihedral angle of 1.8 (1)° between the planes. However, because of steric hindrance, the benzene ring [maximum deviation = 0.006 (2) Å] is not parallel to the pyridine ring [dihedral angle = 37.29 (8)°]. The mol-ecules display numerous inter-molecular π-π inter-actions between the five- and six-membered rings, the shortest centroid-centroid distance being 3.796 (2) Å. There are inter- and intra-molecular O-H⋯O and C-H⋯O hydrogen bonds.

The asymmetric unit contains one half of the formula unit; a centre of inversion is located at the centroid of the compound. The dihedral angle between adjacent isoxazole and benzene rings is 84.0 (2)°. The compound displays intra- and intermolecular π–π stacking interactions between the isoxazole rings, the shortest centroid–centroid distances being 3.837 (3) and 3.634 (3) Å, respectively. The molecules are stacked in columns along the a axis with short Br...Br contacts [3.508 (1) Å].
