6,7-Di­chloro-2,3-bis(pyridin-2-yl)quinox­aline

The title compound, C(18)H(10)Cl(2)N(4), synthesized by the condensation reaction between 4,5-di­chloro­benzene-1,2-di­amine and 1,2-di(pyridin-2-yl)ethane-1,2-dione in boiling acetic acid, has a nearly planar quinoxaline moiety [maximum deviation = 0.070 (1) Å] whose mean plane makes dihedral angle...

Sumario:The title compound, C(18)H(10)Cl(2)N(4), synthesized by the condensation reaction between 4,5-di­chloro­benzene-1,2-di­amine and 1,2-di(pyridin-2-yl)ethane-1,2-dione in boiling acetic acid, has a nearly planar quinoxaline moiety [maximum deviation = 0.070 (1) Å] whose mean plane makes dihedral angles of 40.51 (2) and 39.29 (3)° with the pyridine rings. Within the unit cell, there are no classical hydrogen bonds. Molecules in the structure pack with π–π stacking contacts between the quinoxaline units and nearby pyridine rings with an intercentroid distance of 3.7676 (9) Å.
