The title compound, C 4 H 4 Br 2 N 2 , crystallizes with two molecules in the asymmetric unit. Each molecule forms stacks with its own kind, the stacks being approximately orthogonal to each other. Both Br atoms in molecule 1 form Lewis acid± base interactions with N atoms in molecule 2, with BrÁ Á
The title compound, C 12 H 15 N 3 O, crystallizes with four independent molecules in the asymmetric unit. The fivemembered heterocyclic rings are essentially planar. The crystal packing is stabilized by intra-and intermolecular hydrogen bonds andstacking interactions.
