4,4′-Bis(prop-2-ynyloxy)biphenyl

Abstract

The title compound, C18H14O2, crystallizes with one half-molecule in the asymmetric unit. The molecule 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 interactions are observed in the crystal structure.
