Tröger’s base is a chiral, C2-symmetric compound with a V-shaped geometry. Analogues of the compound are of interest in areas such as molecular recognition and asymmetric catalysis; however, applications have been limited by the type of substituents (generally electron-donating) that could be incorporated on the aryl rings. In this study the structure determination of a tetranitro analogue is reported, in which the dihedral angle between the two aromatic rings is 103.64 (5)°. The crystal chosen for analysis crystallised in enantiopure form from a racemic mixture.
