Abstract
C10H12N2O4 (M r =224.2) crystallizes in the triclinic system, space groupP¯1 witha=8.327(3),b=8.734(3),c=8.453(3) Å;a=63.6(1),β=97.0(1), γ=100.4(1)°;V=541.0(6) Å3,Z=2,D c =1.38 g cm−3,μ(Cu-Kα)=8.7 cm−1, λ=1.5418 Å, F(000)=236. Deviation from theoretic geometry of the benzene ring and from planarity is observed in accordance with theσ-electron-withdrawing character of the NO2 groups and the high steric hindrance of the substituents.
