4-Methyl-5-phenyl-1H-pyrazol-3-ol.

ABSTRACT: The title compound, C(10)H(10)N(2)O, crystallizes with two independent mol-ecules in the asymmetric unit, having closely comparable geometries. The dihedral angles between the 1H-pyrazole and benzene rings in the two mol-ecules are 39.57?(14) and 41.95?(13)°. The two mol-ecules are each connected to neighbouring mol-ecules by pairs of inter-molecular O-H?N hydrogen bonds, forming dimers with R(2) (2)(8) ring motifs. These dimers are further linked into R(4) (4)(10) ring motifs by inter-molecular N-H?O hydrogen bonds, forming chains along [101]. The crystal structure is further stabilized by a C-H?? inter-action.

Project description:The asymmetric unit of the title compound, C(10)H(10)N(2)O, contains two crystallographically independent mol-ecules with similar geometries, which exist in the keto form.
