    Notes: The crystal packing modes of nitrobenzene derivatives, compounds classified as BCLASS = 15 by the Cambridge Structural Database (CSD), have been analysed. Several packing modes have been observed, although two of them, the so-called stacks and pseudo-herringbone, appear as the most populated ones. In 28.4% of the 169 structures that fulfilled the conditions of the search, the molecules are packed to form columns, with the aromatic planes almost parallel. Different ways of stacking within the columns and the way in which these columns pack together to give the whole crystal have been analysed.

    Notes: Nitrobenzene derivatives pack in two main motifs: stacks [see André , Foces-Foces, Cano & Martinez-Ripoll (1997). Acta Cryst. B53, 984–995] and `pseudo- herringbone' together account for some 61.5% of the structures classified as BCLASS = 15 by the Cambridge Structural Database. Several geometrical parameters allow the classification of the `pseudo-herringbone' category into four main motifs. Weak interactions appear to play an important role in this packing mode.
