Abstract: The title compound, C₃₂H₃₀O₄, crystallizes with three different conformers of the same molecule in the asymmetric unit, which explains the unusually large unit cell volume. The supramolecular structure is based on interactions involving the methoxy groups [CO contacts between 3.090 (2) and 3.204 (2) Å, and C-HO contacts between (normalized) 2.40 and 2.71 Å], - stacking of the electron-rich methoxy-substituted rings [centroid-centroid distances of 3.6454 (9)-3.738 (1) Å] and C-H contacts (normalized, 2.62-2.97Å).
