Abstract: | The structure of the title compound, C12H9N5O4, reveals an almost planar molecule (r.m.s. deviation = 0.061 Å), in which the interplanar angle between the phenyl rings is 5.7 (1)° and the largest interplanar angle is that between the phenyl ring and the nitro group of one of the 4‐nitrophenyl substituents [8.8 (3)°]. The observed molecular conformation suggests a delocalization of π‐electrons extended over the diazoamine group and the terminal aryl substituents. Intermolecular N—H⃛O interactions between the twofold screw‐related molecules give rise to helical chains along the [010] direction. Intermolecular C—H⃛O interactions then generate sheets of molecules in the (10) plane, and these sheets are held together by N⃛C and O⃛O π–π interactions. |
