organic compounds
Molecules of furan-2,5-dimethanol, C6H8O3, are linked by O—HO hydrogen bonds involving only the hydroxyl O atoms. Different hydrogen-bonding motifs link the molecules into chains parallel to both the a and b directions, and thus into sheets normal to the c direction containing rhomboidal nets of hydrogen bonds. Molecules of furan-2,5-diylbis(diphenylmethanol), C30H24O3, are linked by multiple weak O—HO hydrogen bonds to form hydrogen-bonded dimers lying about a twofold axis. (2-Furyl)diphenylmethanol, C17H14O2, is isomorphous with triphenylmethanol, Ph3COH.
