Abstract: The synthesis and crystal structure of 4,11-dimethyl-2,13-di-m-tolyltribenzo[b,e,g][1,4]dioxocine-7,8-dicarbonitrile are reported. X-ray diffraction analysis reveals a rigid dioxocine core with m-tolyl substituents adopting torsional angles of 25–40°. The crystal packing is stabilized by C-H···N hydrogen bonds (2.6 Å) and π-π stacking interactions (3.4 Å) between dicarbonitrile groups, forming dimeric motifs. These structural insights provide a foundation for designing dioxocine-based functional materials.
