9,9-Dimethyl-9,10-dihydroanthracene.

In the title compound, C(16)H(16), the central benzene ring adopts a boat conformation, with a dihedral angle of 34.7 (9)° between the mean planes of the two fused benzene rings. The two methyl groups at the apex of the central benzene ring are in axial and equatorial conformations. The crystal packing is stabilized by weak C-H⋯π inter-molecular inter-actions.
