title: 2-(9,9-Diethyl-9H-fluoren-2-yl)-1-benzofuran.
abstract: In the title compound, C(25)H(22)O, the dihedral angle between the benzofuran and fluorene ring systems is 9.06 (6)°, and that between the two benzene rings of the fluorene system is 1.78 (12)°. Weak inter-molecular C-H⋯π inter-actions help to stabilize the crystal structure.
