Deskripsi
In the title compound, C14H11BrF3N5O2, the pyrimidine ring adopts a flattened envelope conformation with sp3-hybridized carbon as the flap [deviation = 0.177 (3) Å]. The dihedral angle between tetrazole and bromophenyl rings is 84.3 (1)°. In the crystal, molecules are linked into centrosymmetric dimers by pairs of N—H...N hydrogen bonds.
