9,9-Diethyl-7-ethynyl-N,N-diphenyl-9H-fluoren-2-amine

Abstract

In the title compound, C31H27N, the fluorene unit is approximately planar (r.m.s deviation = 0.0255 Å). The dihedral angles between the fluorene fused ring system and two phenyl rings are 88.37 (5) and 66.31 (6)°. Weak intermolecular C—H...π(ring) interactions help to stabilize the crystal structure.
