Tris[4-(4-nitrophenyl)-3-aza-3-butenyl]amine: pi-stacked chains of hydrogen-bonded R(2)(2)26 dimers.
In the title compound {alternative name: N'-(4-nitrobenzylidene)-N,N-bis[2-(4-nitrobenzylideneamino)ethyl]-1,2-ethanediamine}, C27H27N7O6, the three independent NCH2CH2N=CHC6H4NO2 fragments all exhibit different conformations, resulting from the different direction-specific intra- and intermolecular interactions experienced. The molecules are linked by a single C-H...O hydrogen bond into centrosymmetric R(2)(2)(26) dimers, which are linked by pi-pi stacking interactions into [111] chains and, more weakly, into (01-1) sheets.
