Abstract
In the title compound, the dihydroquinoxaline units are both essentially planar and the dihedral angle between their mean planes is 64.82 (2)°. In the crystal, C—H⋯O hydrogen bonds form chains along the b-axis direction which are joined by π-stacking and C—H⋯π(ring) interactions into the full three-dimensional network structure.
In the title compound, C31H24N4O2, the dihydroquinoxaline units are both essentially planar with the dihedral angle between their mean planes being 64.82 (4)°. The attached phenyl rings differ significantly in their rotational orientations with respect to the dihydroquinoxaline planes. In the crystal, one set of C—H⋯O hydrogen bonds form chains along the b-axis direction, which are connected in pairs by a second set of C—H⋯O hydrogen bonds. Two sets of π-stacking interactions and C—H⋯π(ring) interactions join the double chains into the final three-dimensional structure.
期刊介绍：
Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
