摘要
In the mol-ecule of the title compound, C19H 17ClN2O4, the quinoxaline ring system is planar [maximum deviation = 0.013 (3) Å] and oriented at a dihedral angle of 80.18 (3)° with respect to the benzene ring. In the crystal structure, inter-molecular C - H⋯N inter-actions link molecules into chains. π-π contacts between the quinoxaline systems [centroid-centroid distance = 3.654 (1) Å] may further stabilize the structure.
