(E)-1,1,4,4-Tetraphenylbut-2-yne-1,4-diol

The molecule of the title compound, C28H22O2, is centrosymmetric with the inversion centre located at the mid-point of the C[triple-bond]C bond [1.178 (5) Å]. The hydroxyl groups therefore lie on either side of the molecule. The crystal structure is stabilized by O—H...O hydrogen bonds, leading to the formation of a linear supramolecular chain along the b axis
