title: 4,4'-Bis(prop-2-yn-yloxy)biphen-yl.
abstract: 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.
