Abstract

The title compound, C13H9BrF3N5O, crystallizes with two independent molecules in the asymmetric unit. The pyrimidine rings of the molecules are planar [maximum deviations 0.053 (3) and 0.012 (3)Å], while the triazine rings adopt flattened half-boat conformations with the p-bromophenyl rings in the flagpole positions. The crystal packing is stabilized by a three-dimensional network of intermolecular N-H...N, N-H...O and N-H...F hydrogen bonds.
