Abstract
In comparison to previous results, the bond lengths C(1)-C(2) and C(1) -C(6) (IUPAC numbering: C4-3a, C4-C5) in the title compound are signif icantly shortened. The endocyclic angle C(3)-C(4)-C(5) (IUPAC numberin g: C7a-C7-C6) is, in contrast to those in nitro-substituted benzene ri ngs, smaller than 120-degrees. A polymethinic structure of the dinitro benzofurazan fragment is assumed. Stacking between the phenyl and fura zan rings indicates weak pi-electron interactions.
