Phenyl acridine-9-carboxyl-ate.

ABSTRACT: The acridine ring system and the benzene ring in the title compound, C(20)H(13)NO(2), are oriented at a dihedral angle of 6.4?(2)°. The carboxyl group is twisted at an angle of 83.6?(2)° relative to the acridine skeleton. The mol-ecules in the crystal are arranged in stacks along the b axis, with two of the acridine rings involved in multiple ?-? inter-actions [centroid-centroid distances in the range 3.536?(2)-3.894?(2)?Å]. Stacks arranged parallel are linked via C-H?? inter-actions, forming layers in the ac plane that are in contact with adjacent, inversely oriented layers via other C-H?? inter-actions, giving rise to double layers. The inversely oriented double layers inter-act dispersively. The acridine units are parallel within the parallel-oriented stacks, but inclined at an angle of 79.6?(2)° in the inversely oriented stacks.
