Semisynthetic roxburghin tetra­methyl ether

The title mol­ecule, (E)-2,3′,4,5-tetra­methoxy­stilbene, C(18)H(20)O(4), is virtually planar. The angle between the two benzene rings is 4.06 (6)°. The inter­molecular inter­actions present in the structure are weak. There are C—H⋯O hydrogen bonds and C—H⋯π-electron ring inter­actions. The mol­ecul...

description The title mol­ecule, (E)-2,3′,4,5-tetra­methoxy­stilbene, C(18)H(20)O(4), is virtually planar. The angle between the two benzene rings is 4.06 (6)°. The inter­molecular inter­actions present in the structure are weak. There are C—H⋯O hydrogen bonds and C—H⋯π-electron ring inter­actions. The mol­ecules are ordered into planes that are parallel to ([Image: see text]01). The distance between adjacent planes is about 3.3 Å and therefore π–π electron inter­actions between the aromatic planes are also plausible.
