5-(Biphenyl-4-yl)-3-(3-meth-oxy-benzyl-idene)furan-2(3H)-one.

In the title compound, C(24)H(18)O(3), the dihedral angles between the mean planes of the five-membered furan ring and the meth-oxy-substituted benzene and the adjacent and outer biphenyl benzene rings are 2.43 (7), 4.48 (7) and 30.47 (8)°, respectively. The crystal packing is stabilized by weak C-H⋯O and C-H⋯π inter-molecular hydrogen bonds and π-π stacking inter-actions [centroid-centroid distances = 3.8752 (8) and 3.8331 (8) Å].
