(E)-1-(Furan-2-yl)-3-(2,4,5-trimeth-oxy-phen-yl)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 meth-oxy 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 inter-actions link the mol-ecules into a sheet parallel to ([Formula: see text]02). An inter-molecular π-π inter-action 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.
