title: 2-[(1R*,4R*)-1,4-Dihy-droxy-cyclo-hex-yl]acetic acid.
abstract: The title compound, C(8)H(14)O(4), is an isolation product of the aerial parts of Senecio desfontanei. The acetic acid group is oriented at a dihedral angle of 48.03 (9)° with respect to the basal plane of the cyclo-hexane-1,4-diol chair. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring with an envelope conformation. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, resulting in R(3) (3)(20) ring motifs and C(2) O-H⋯O-H⋯O-H⋯ chains. Overall, a three-dimensional polymeric network arises. A C-H⋯O contact is also present.
