Figure 2
The mol­ecular structures of (I)[link], (II)[link] and (III)[link], showing the atom-numbering scheme. In each case, the nitro-substituted ring is labelled A. Displacement ellipsoids are drawn at the 50% probability level. H atoms are represented by spheres of arbitrary radii and bear the same number as the C atom to which they are attached.
