Crystal structure of 1,3-bis(2,3-dimethylquinoxalin-6-yl)benzene

Abstract

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