C15H18O5 is orthorhombic, P212121. The unit-cell dimensions at 293 K are a = 6.526(3), b = 10.247(4), c =21.008(13)Å, V = 1404.8(12)Å3, Dx = 1.316 g/cm3, and Z = 4. The R value is 0.044 for 1288 observed reflections. The A, B and C rings adopt chair, twist, and half-chair conformations. The absolute configuration is inferred from the C6 stereochemistry of (+)-cedrol. The crystal structure is stabilized by an O-H···O hydrogen bond and van der Waals forces.
