1-Bromo-2,4-dinitrobenzene

R. Kruszynski and W. Czestkowski

Abstract: All interatomic distances in the title compound, C₆H₃BrN₂O₄, previously reported by Watson [Nature (London) (1960), 188, 1102-1103] and Gopalakrishna [Acta Cryst. (1969), A25, S-150], can be considered to be normal. The benzene ring is very slightly distorted from planarity. The weighted least-squares planes calculated through the atoms of the nitro groups make angles of 42.3  (3) and 9.7  (3)° with the benzene ring plane, for the 2- and 4-nitro groups, respectively. In the crystal, one weak C-HO intermolecular hydrogen bond and two stacking interactions can be found. The structure is assembled into a three-dimensional net via these interactions.
