چکیده
The title compound, C(30)H(26)O(2), was prepared by the reaction of a Wittig reagent and 2-methoxy-benzaldehyde. The mol-ecule lies about an inversion centre located at the midpoint of the C-C bond between the inner benzene rings. The crystal structure is stabilized by C-H⋯π inter-actions.

The title compound, C(18)H(14)O(2), crystallizes with one half-mol-ecule in the asymmetric unit. The mol-ecule lies on an inversion center, located at the mid-point of the central C-C bond. As a result, the benzene rings are coplanar. No classical hydrogen bonds or stacking inter-actions are observed in the crystal structure.
