| Popis: | The complete molecule of the title compound, C26H20N2O2, is generated by a crystallographic twofold axis. The torsion angle between the terminal and central benzene rings is −32.5 (2)°. The torsion angle along the inner helical rim of the molecule is −18.8 (2)° with each other. The C...C distance between the terminal rings is 3.016 (2) Å. In the crystal, weak C—H...N hydrogen bonds are observed. |
