In (I), C14H14O2, the dihydrobenzene ring adopts a flattened boat conf
ormation and the hydroxyl group is involved in an O-H ... O intramolec
ular hydrogen bond. In (II), C21H16O2, the dihydronaphthalene ring sys
tem is planar and makes a dihedral angle of 70.06(7)degrees with the n
aphthalene ring system; the hydroxyl group forms O-H ... O intermolecu
lar hydrogen bonds.
