10-(4-Methyl­benzyl­idene)anthracen-9(10H)-one

In the title compound, C(22)H(16)O, the six-membered ring within the anthrone moiety adopts a shallow boat conformation, with puckering parameters Q = 0.2860 (17) Å, Θ = 99.1 (3)° and Φ = 114.8 (3)°. The dihedral angle between the outer benzene rings is 26.53 (8)°. The mean plane through the anthrone ring system makes a dihedral angle of 38.73 (6)° with the pendant benzene ring. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds into zigzag chains propagating along the c-axis direction and weak C—H⋯π inter­actions further consolidate the structure.
