The title compound, C 14 H 12 BrN 2 O + ÁClO 4 À , was synthesized from the parent 2-aminooxazole and acetylacetone and characterized by 1 H NMR and single-crystal X-ray diffraction. The bromophenyl fragment and the essentially planar ninemembered bicyclic system form a dihedral angle of 10.50 (11)
In the title compound, C 10 H 10 Br 2 O 2 , the angle between the dibromovinyl group and the benzene ring is 42.2 (2) .
The molecule of the title compound, C 22 H 22 O 2 , possesses a crystallographically imposed twofold axis. The two terminal phenyl rings both make a dihedral angle of 82.5 (2) with the central benzene ring. The crystal packing is stabilized mainly by van der Waals forces.
In the title compound, C 11 H 10 N 6 O 3 , the mean planes of the benzotriazole ring system and the 1,3,5-triazine ring make a dihedral angle of 89.3 (3) . The crystal packing is stabilized by stacking interactions and van der Waals forces.
