(E)-1-(Furan-2-yl)-3-(2,4,5-trimeth­oxy­phen­yl)prop-2-en-1-one

In the title chalcone derivative, C(16)H(16)O(5), the dihedral angle between the furan and benzene rings is 2.06 (17)°. The two meth­oxy groups at the ortho and para positions are essentially coplanar with the benzene ring [C—O—C—C angles = −1.0 (5) and 178.5 (3)°], whereas the third one at the meta position is slightly twisted [C—O—C—C = 9.6 (5)°]. In the crystal, weak C—H⋯O inter­actions link the mol­ecules into a sheet parallel to ([Image: see text]02). An inter­molecular π–π inter­action between the furan and benzene rings is present [centroid–centroid distance = 3.772 (2) Å]. A short C⋯C contact [3.173 (5) Å] is also observed between neighbouring furan rings.
