Abstract:
Molecules of the title compound, C(16)H(14)O, are chiral and crystallize in space group P-4 with Z' = 2, and with one R and one S molecule in the asymmetric unit. The conformations of the phenyl rings in the two independent molecules differ slightly. Supramolecular organization in the crystal is via tetrameric O-H. H(O) hydrogen-bonded synthons formed separately by each conformer. These tetrameric synthons stack along the c axis via C[triple-bond]C-H.O(H) hydrogen bonds. The only link between the conformer stacks is provided by weaker C(methylene)-H and C(phenyl)-H interactions with pi(arene) density.
