10-Hydroxy-10-(1,3-thiazol-2-ylmethyl)phenanthren-9(10H)-one

In the title phenanthrenone compound, C18H13NO2S, the dihydrophenanthrene ring system is not planar, with its central ring distorted to a screw-boat conformation. The essentially planar thiazole ring [maximum deviation = 0.005 (1) Å] is inclined at an interplanar angle of 23.36 (5)° with respect to the mean plane through the dihydrophenanthrene ring system. In the crystal packing, intermolecular O—H...N hydrogen bonds link the molecules into infinite chains along the a axis. Weak intermolecular C—H...π interactions further stabilize the crystal packing.
