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

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.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > 2sigma(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
