In the title compound, C 18 H 12 O 2 , the benzene rings are inclined to one another by 66.79 (7)°. The five-membered ring is almost planar with a maximum deviation of 0.014 (1) Å. In the crystal, the molecules are linked by pairs of weak C—H...O interactions into centrosymmetric dimers. These dimer...

, the benzene rings are inclined to one another by 66.79 (7)°. The five-membered ring is almost planar with a maximum deviation of 0.014 (1) Å. In the crystal, the molecules are linked by pairs of weak C—H...O interactions into centrosymmetric dimers. These dimers are linked by C—H...π interactions, forming a three-dimensional structure. |
