6,7-Dichloro-3-(2,4-dichloro­benz­yl)­quinoxalin-2(1H)-one

In the title compound, C(15)H(8)Cl(4)N(2)O, the quinoxaline ring system is almost planar, with a dihedral angle between the benzene and pyrazine rings of 3.1 (2)°. The 2,4-dichloro­phenyl ring is approximately perpendicular to the pyrazine ring, with a dihedral angle of 86.47 (13)° between them. The...

Sumario:In the title compound, C(15)H(8)Cl(4)N(2)O, the quinoxaline ring system is almost planar, with a dihedral angle between the benzene and pyrazine rings of 3.1 (2)°. The 2,4-dichloro­phenyl ring is approximately perpendicular to the pyrazine ring, with a dihedral angle of 86.47 (13)° between them. The crystal packing features inter­molecular N—H⋯O hydrogen bonds and π–π stacking inter­actions, with centroid–centroid distances in the range 3.699 (3)–4.054 (3) Å.
