Crystal structure and Hirshfeld surface analysis of 3-phenyl-1-{3-[(3-phenylquinoxalin-2-yl)oxy]propyl}-1,2-dihydroquinoxalin-2-one

In the title compound, C31H24N4O2, the quinoxaline units are distinctly non-planar and twisted end-to-end. In the crystal, C — H...O and C — H...N hydrogen bonds link the molecules into chains extending along the a-axis direction. The chains are linked through π -stacking interactions between inversion-related quinoxaline moieties.
