The crystal structure of (E)-2-ethyl-N-(4-nitrobenzylidene)aniline: three-dimensional supramolecular assembly mediated by C—H...O hydrogen bonds and nitro...π(arene) interactions

Abstract

In the molecule of the title compound, C15H14N2O2, the 2-ethylphenyl group is disordered over two sets of atomic sites having occupancies of 0.515 (19) and 0.485 (19), and the dihedral angle between the two partial-occupancy aryl rings is 6(2)°. A combination of C—H...O hydrogen bonds and nitro...π(arene) interactions links the molecules into a continuous three-dimensional framework structure. Comparisons are made with the structures of some related compounds.
