title: 2-Dibutyl-amino-1-(2,7-dichloro-9H-fluoren-4-yl)ethanol.
abstract: In the title compound, C(23)H(29)Cl(2)NO, the fluorene ring is essentially planar, with a maximum deviation from the mean plane of 0.041 (1) Å. The amine group adopts a pyramidal configuration, the sum of the bond angles being 336.2 (3)°. In the crystal, the mol-ecules are linked into dimers by inter-molecular O-H⋯N and C-H⋯O hydrogen bonds. Weak C-H⋯π and π-π [centroid-centroid distance = 3.7544 (7) Å] inter-actions are also observed.
