(2-Amino-phen-yl)[(5S)-5-hydr-oxy-3,5-dimethyl-4,5-dihydro-1H-pyrazol-1-yl] methanone

Abstract

In the mol-ecule of the title compound, C12H15N 3O2, the pyrazole ring is oriented at a dihedral angle of 49.64 (6)° with respect to the benzene ring. Intra-molecular O - H⋯O, N - H⋯O and C - H⋯O inter-actions result in the formation of a trifurcated hydrogen bond. In the crystal structure, inter-molecular N - H⋯O and O - H⋯N hydrogen bonds link the mol-ecules, forming a network structure. © 2009 Arfan et al.
