Abstract

In comparison to previous results, the bond lengths C(1)-C(2) and C(1)-C(6) (IUPAC numbering: C4-C3a, C4-C5) in the title compound are significantly shortened. The endocyclic angle C(3)C(4)-C(5) (IUPAC numbering: C7a-C7-C6) is, in contrast to those in nitro-substituted benzene rings, smaller than 120 o . A polymethinic structure of the dinitrobenzofurazan fragment is assumed. Stacking between the phenyl and furazan rings indicates weak π-electron interactions
