title: 2,10-Bis(3-bromo-phen-yl)-3,7,11,15-tetra-oxa-8,16-diaza-tricyclo-[12.2.1.1]octa-deca-1(16),6(18),8,14(17)-tetra-ene.
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].
