✦ Synopsis
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 ÁN distances of 3.078 (4) and 3.264 (4) A Ê .
