1,4a,7-Trimethyl-7-vinyl-1,2,3,4,4a,4b,5,6,7,8,10,10a-dodeca­hydro­phenanthrene-1-carboxylic acid

The title compound, also known as isopimaric acid, C(20)H(30)O(2), was isolated from slash pine rosin. There are two unique mol­ecules in the unit cell. The two cyclo­hexane rings have classical chair conformations. The cyclo­hexene ring represents a semi-chair. The mol­ecular conformation is stabil...

description The title compound, also known as isopimaric acid, C(20)H(30)O(2), was isolated from slash pine rosin. There are two unique mol­ecules in the unit cell. The two cyclo­hexane rings have classical chair conformations. The cyclo­hexene ring represents a semi-chair. The mol­ecular conformation is stabilized by weak intra­molecular C—H⋯O hydrogen-bonding inter­actions. The mol­ecules are dimerized through their carboxyl groups by O—H⋯O hydrogen bonds, forming R (2) (2)(8) rings.
