2,6-Di­nitro­toluene

Crystals of 2,6-di­nitro­toluene, C₇H₆N₂O₄, were obtained from a methanol solution of the mixture of 2,6- and 2,4-di­nitro­toluene. The P2₁2₁2₁ space group shows the compound is chiral, but the absolute configuration was not determined reliably. The nitro group planes are inclined to the benzene plane with dihedral angles of 53.1 (1) and 38.1 (1)°, respectively. The repulsion between methyl and nitro groups results in a rather small C—C—C angle of 112.6 (2)° within the benzene ring.
