The five-membered 1,3-dioxolane ring adopts an envelope form, with the C atom bonded to the olefin side chain as the flap, which deviates from the mean plane through the other four atoms by 0.564(7). The 1,3-dioxole ring fused to the benzene ring adopts a flattened envelope form, with the C atom between the two O atoms as the flap, which deviates from the mean plane through the other four atoms by 0.215(7). The CC=CC olefin moiety is essentially planar and makes a dihedral angle of 87.1(3) with the benzene ring. An intramolecular OH...O hydrogen bond supports the molecular conformation, enclosing an S(11) graph-set motif. In the crystal, intermolecular CH...O hydrogen bonding links the molecules into a tape running along the b axis. Furthermore, other weak CH...O hydrogen bonds and a CH... interaction connect the tapes into a sheet structure parallel to (100).", }
