| Summary: | The title compound, C7H14O2, is a vicinal diol derived from cycloheptane with cis-orientated hydroxy groups. The molecules shows no non-crystallographic symmetry. The O—C—C—O torsion angles of both molecules present in the asymmetric unit [−66.4 (2) and −66.9 (2)°] are similar to those in trans-configured cyclohexane derivatives (including pyranoses) as well as rac-trans-cycloheptane-1,2-diol, but smaller than those in trans-configured cyclopentane derivatives (including furanoses). In the crystal structure, O—H...O hydrogen bonds furnish the formation of sheets parallel to [110].
