(E)-1-(Furan-2-yl)-3-(2,4,5-trimeth-oxy-phen-yl)prop-2-en-1-one.

ABSTRACT: 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 ?-? 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.
