Abstract: The title compound, C₂₃H₂₂O₄, contains two crystallographically independent molecules in the asymmetric unit. In both molecules, the indan ring system is almost planar, and the cyclopentane and cyclohexanone rings adopt distorted envelope conformations. In the crystal structure, the molecules exist as O-HO hydrogen-bonded dimers.
