Crystal structure and Hirshfeld surface analysis of 3-phenyl-1-{3-[(3-phenyl-quinoxalin-2-yl)-oxy]prop-yl}-1,2-di-hydro-quinoxalin-2-one.

Abstract

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 mol-ecules into chains extending along the a-axis direction. The chains are linked through π-stacking inter-actions between inversion-related quinoxaline moieties.
