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)degrees. The two molecules are each connected to neighbouring molecules by pairs of intermolecular O-H center dot center dot center dot 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 center dot center dot center dot O hydrogen bonds, forming chains along [101]. The crystal structure is further stabilized by a C-H center dot center dot center dot pi interaction.
