Its mean plane is inclined to the benzene ring by 7.99 (19)°. The molecule has a trans conformation about the bridging C=C bonds of the allyidene chain. In the crystal, molecules are linked via pairs of C-H？O hydrogen bonds, forming inversion dimers. The dimers are linked by further C-H.·O hydrogen bonds, forming sheets lying parallel to (101).
