2,6-Dimethylphenyl acridine-9-carboxylate
Abstract
In the title compound, C22H17NO2, the acridine ring system and the benzene ring are oriented at a dihedral angle of 37.7 (1)°. The carboxyl group is twisted at an angle of 67.7 (1)° relative to the acridine skeleton. In the crystal, molecules are arranged in stacks along the b axis, with all of the acridine rings involved in multiple π–π interactions [centroid–centroid distances in the range 3.632 (2)–4.101 (2) Å]. The acridine moieties are parallel within the stacks, but inclined at an angle of 52.7 (1)° in adjacent stacks.
