title: 4,4'-Bis[2-(3,5-dimeth-oxy-phen-yl)ethen-yl]biphen-yl.
abstract: The title compound, C(32)H(30)O(4), crystallizes with three different conformers of the same mol-ecule in the asymmetric unit, which explains the unusually large unit cell volume. The supra-molecular structure is based on inter-actions involving the meth-oxy groups [C⋯O contacts between 3.090 (2) and 3.204 (2) Å, and C-H⋯O contacts between (normalized) 2.40 and 2.71 Å], π-π stacking of the electron-rich meth-oxy-substituted rings [centroid-centroid distances of 3.6454 (9)-3.738 (1) Å] and C-H⋯π contacts (normalized, 2.62-2.97Å).
