(E)-2-{Ethyl[4-(4-nitrophenyldiazenyl)phenyl]amino}ethyl anthracene-9-carboxylate

Abstract

The crystal structure of the title compound, C31H26N4O4, displays a trans conformation for the nitrophenyldiazenyl portion of the molecule. Packing diagrams indicate that weak C—H...O hydrogen bonds, likely associated with a strong dipole moment present in the molecule, dictate the arrangement of molecules in the crystal structure.
