Bottom Line: The cyclo-hexane ring has a chair conformation and the cyclo-hexene ring a distorted half-boat conformation.The two independent mol-ecules are connected into a dimer via O-H⋯O hydrogen bonds.The dimers are associated into supra-molecular chains along c via C-H⋯O contacts.

ABSTRACT
In the two, almost identical, mol-ecules in the asymmetric unit of the title compound [systematic name: (E)-3-methyl-5-(1,2,4a,5-tetra-methyl-1,2,3,4,4a,7,8,8a-octa-hydro-naphthalen-1-yl)pent-2-enoic acid], C(20)H(32)O(2), the rings are trans fused. The cyclo-hexane ring has a chair conformation and the cyclo-hexene ring a distorted half-boat conformation. The two independent mol-ecules are connected into a dimer via O-H⋯O hydrogen bonds. The dimers are associated into supra-molecular chains along c via C-H⋯O contacts.
