✦ Synopsis

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) .
