【 摘 要 】

In the title compound, C21H24O4 (systematic name: 4,5′-diallyl-2,2′,3′-tri­meth­oxy­diphenyl ether), the aromatic rings lie almost perpendicular to each other [dihedral angle = 85.96 (2)°]. The allyl side chains show similar configurations, with Car—C—C=C (ar = aromatic) torsion angles of −123.62 (12) and −115.54 (12)°. A possible weak intra­molecular C—H⋯O inter­action is observed. In the crystal, mol­ecules are connected by two C—H⋯O hydrogen bonds, forming undulating layers lying parallel to the bc plane. Weak C—H⋯π and π–π stacking inter­actions also occur.
