J. Liu and W. Yu

Abstract: The title compound [systematic name: 9-(9H-fluoren-3-yl)-9H-fluorene], C₂₆H₁₈, was obtained unintentionally as the product of the synthesis of a compound based on fluorene-thiophene units. The two fluorene rings are connected through C atoms in the 3- and 9'-positions, and the dihedral angle between the mean planes of the two fluorene units is 78.57 (6)°.
