title: 2,4-Dimeth-oxy-6-[(E)-2-(4-meth-oxy-phenyl)ethen-yl]benzaldehyde.
abstract: There are two conformationally similar mol-ecules in the asymmetric unit of he title compound, C18H18O4, in which the dihedral angles between the benzene rings are 23.54 (12) and 31.11 (12)°. In the crystal, C-H⋯π inter-actions (minimum H⋯ring centroid distance = 2.66 Å) link the mol-ecules into a layered structure extending down a.
