title: N-(9H-Fluoren-9-yl-idene)-4-methyl-aniline.
abstract: In the title compound, C(20)H(15)N, the fluorene unit is essentially planar [r.m.s. deviation 0.0334 Å] and the benzene ring bound to the imine N atom bears a methyl group which is nearly coplanar [dihedral angle 0.5 (1)°]. The dihedral angle between the substituent benzene ring and the 9H-fluoren-9-imine unit is 71.1 (3)°. Inter-molecular π-π inter-actions between the benzene rings of adjacent fluorene units [centroid-centroid distance 3.8081 (13) Å] are present in the crystal structure, resulting in a one-dimensional supra-molecular architecture.
