title: (E)-1-(4-Meth-oxy-phen-yl)-3-(3,4,5-trimeth-oxy-phen-yl)prop-2-en-1-one.
abstract: The title compound, C(19)H(20)O(5), was synthesized by reaction of 4-meth-oxy-acetophenone and 3,4,5-trimeth-oxy-benzaldehyde. The aromatic rings form a dihedral angle of 36.39 (7)°. Two intramolecular C-H⋯O hydrogen bonds occur. The crystal packing features weak C-H⋯O inter-actions.
