title: Crystal structure of 1,4,5,6,7,8,9,10,11,12,13-undeca-hydro-cyclo-dodeca[c]pyrazol-3-ol.
abstract: The title compound, C13H22N2O, crystallized as a pyrazolol tautomer. The 12-membered macrocycle has a distorted chair conformation. In the crystal, mol-ecules are linked via pairs of O-H⋯N hydrogen bonds, forming inversion dimers. The dimers are linked via N-H⋯π and C-H⋯π inter-actions, forming slabs parallel to the bc plane.
