Abstract C10H12N2O4 (M r=224.2) crystallizes in the monoclinic system, space groupP21/mwitha=15.462(4),b=7.926(3),c=8.972(3) Å;β=90.2(1)°;V=1099.5(6) Å3;Z=4;D c=1.35 gcm−3;μ(Cu-Kα)=8.6 cm−1; λ=1.5418 Å;F(000)=472. The position of the molecule on a crystallographic mirror plane forces the NO2 plane to be normal to the benzene ring. Theσ-electron-withdrawing character of the NO2 groups induces a deformation on the geometry of the benzene.
