The title compound, C26H22N4 (I), was synthesized by C-H iridium-catalyzed borylation followed by Suzuki coupling. The mol-ecular structure of (I) consists of a central benzene ring with 3-di-methyl-quinoxalin-6-yl groups at the 1 and 3 positions. These 2,3-di-methyl-quinoxalin-6-yl groups twist significantly out of the plane of the benzene ring. There are inter-molecular π-π inter-actions which result in a two-dimensional extended structure. The layers extend parallel to the ab plane and stack along the c axis.
