1,2,3,4,5,7-Hexanitrocubane

R. Gilardi, R. J. Butcher and M.-X. Zhang

Abstract: The hexanitrocubane structure, C₈H₂N₆O₁₂, reported herein, is one of the last in the series of nitrocubanes, ranging from mono- to octanitrocubane. In this molecule, the H atoms participate in short hydrogen-bonding contacts to the nitro O atoms in adjoining molecules [2.50  (1)  Å], thus linking molecules into a two-dimensional sheet in the bc plane. In addition, the OO contacts in hexanitrocubane are shorter than van der Waals contact distances. The shortest of these [2.766  (3)  Å] involve the O atoms of one of the attached nitro groups. These contacts involve molecules in an extended two-dimensional sheet parallel to the ab plane.
