Perpendicular arrangement of two nitro groups of adjacent molecules was found in 104 structural fragments deposited in the Cambridge Structural Database. In the most cases, this non-hydrogen bonding ONO2⋯π(N)NO2 interaction is shorter than 3 A. Ab initio calculations of the interaction energy indicates the attractive nature of this interaction, comparable to the Eint of C–H⋯O.
