Abstract: The medium-sized heterocyclic title compound, C₂₁H₁₇Cl₄NO₃, crystallizes with two crystallographically independent molecules in the asymmetric unit. The cyclopentane rings adopt half-chair conformations. Symmetry-related molecules are linked via O-HO hydrogen bonds to form dimers, which are arranged into one-dimensional chains along the [100] direction. C-H and - interactions were also observed in the crystal structure.
