title: (4aR,8aS,9aR,10aS)-8a,9a-difluoro-1,4,4a,5,8,8a,9,9a,10,10a-decahydroanthracene-4a,10a-diol hemihydrate.
abstract: The title compound, C(14)H(18)F(2)O(2)·0.5H(2)O, a hemihydrate of a C(s)-symmetric unsaturated difluorodiol, crystallizes in the centrosymmetric space group P2/m (Z = 4). The asymmetric unit contains two crystallographically independent difluorodiol half-molecules, occupying the mirror planes at (x, 0, z) and (x, 1/2, z), and half a molecule of water, lying on the twofold axis at (0, y, 0). Four difluorodiol molecules self-assemble around each solvent water molecule via O-H...O hydrogen bonds in a near tetrahedral symmetry to generate a cylindrical column-like architecture.
