ABSTRACT
The title compound, C(24)H(22)N(2)O(2), was prepared by condensation of 1,2-bis-(4-ethoxy-phen-yl)ethane-1,2-dione and 1,2-diamino-benzene. The asymmetric unit contains one half-mol-ecule, close to a twofold axis. The plane of the quinoxaline ring is twisted with respect to the planes of the two ethoxy-phenyl ring systems, exhibiting dihedral angles of 39.95â
(9)°. The crystal packing is dominated by weak C-Hâ¯π inter-actions. No classical hydrogen bonds or stacking inter-actions are observed.
