2,3-Bis(4-ethoxy­phen­yl)quinoxaline

The title compound, C(24)H(22)N(2)O(2), was prepared by condensation of 1,2-bis­(4-ethoxy­phen­yl)ethane-1,2-dione and 1,2-diamino­benzene. The asymmetric unit contains one half-mol­ecule, close to a twofold axis. The plane of the quinoxaline ring is twisted with respect to the planes of the two eth...

description The title compound, C(24)H(22)N(2)O(2), was prepared by condensation of 1,2-bis­(4-ethoxy­phen­yl)ethane-1,2-dione and 1,2-diamino­benzene. The asymmetric unit contains one half-mol­ecule, close to a twofold axis. The plane of the quinoxaline ring is twisted with respect to the planes of the two ethoxy­phenyl ring systems, exhibiting dihedral angles of 39.95 (9)°. The crystal packing is dominated by weak C—H⋯π inter­actions. No classical hydrogen bonds or stacking inter­actions are observed.
