title: (1RS,2RS,3SR,5RS,7RS)-2,5-Dichloro-8-oxabicyclo-[5.1.0]octan-3-ol.
abstract: In the title compound, C(7)H(10)Cl(2)O(2), the seven-membered ring displays a chair conformation. In the crystal, the hy-droxy H atom is equally disordered over two orientations, and links with an adjacent mol-ecule via an O-H⋯O hydrogen bond in both cases. Weak inter-molecular C-H⋯O hydrogen bonding is also a feature of the crystal structure.
