Hydrogen bonding and C-H•••O interactions in 4-phenanthrenemethanol at 150 K

The title compound, C15H12O, crystallizes in the centrosymmetric space group I4(1)/a with one molecule in the asymmetric unit. In the single hydrogen bond, the H atom is ordered, the O-D . . . O-A distance is 2.788 (1) Angstrom and the O-H . . . O angle is 176 (1)degrees. Each hydroxyl group forms hydrogen bonds with two other hydroxyl groups and the resulting chains of interactions, in four non-linked subsets of molecules, propagate along [001]. The single leading intermolecular C-H . . . O interaction has an H . . . O distance of 2.81 Angstrom and a C-H . . . O angle of 140 degrees; the single leading intramolecular C-H . . . O interaction has an H . . . O distance of 2.24 Angstrom and a C-H . . . O angle of 152 degrees. The phenanthrene core is less nearly planar in this structure than in the room temperature structure of phenanthrene-4-carboxylic acid.
