Formation of non-centrosymmetric dimers in (1S*,4aR*,8aR*)-decahydronaphthalene-1-carboxylic acid
The all-cis racemate of the title compound, C11H18O2, crystallizes in the chair-chair conformation that places the carboxyl group in an equatorial postion. The space group is centrosymmetric but the compound aggregates as dimers whose components are related by a C2 axis [OO = 2.665 (3) Å and O—HO = 177°]. In the crystal structure, one C—HO=C close contact is found.
