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

The title compound, C(10)H(10)N(2)O, crystallizes with two independent mol­ecules in the asymmetric unit, having closely comparable geometries. The dihedral angles between the 1H-pyrazole and benzene rings in the two mol­ecules are 39.57 (14) and 41.95 (13)°. The two mol­ecules are each connected to...

description The title compound, C(10)H(10)N(2)O, crystallizes with two independent mol­ecules in the asymmetric unit, having closely comparable geometries. The dihedral angles between the 1H-pyrazole and benzene rings in the two mol­ecules are 39.57 (14) and 41.95 (13)°. The two mol­ecules are each connected to neighbouring mol­ecules by pairs of inter­molecular 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 inter­molecular N—H⋯O hydrogen bonds, forming chains along [101]. The crystal structure is further stabilized by a C—H⋯π inter­action.
