The pyrazole ring makes a dihedral angle of 29.04 (5)° with the benzene ring. The mol-ecular structure is stabilized by an intra-molecular C - H?O hydrogen bond which generates an S(9) ring motif. In the crystal, molecules are linked via N - H?O and C - H?N hydrogen bonds into a two-dimensional network parallel to the ab plane. The crystal structure is further consolidated by weak C - H?? inter-actions.data-to-parameter ratio = 27.7mean ?(C-C) = 0.001 ÅR factor = 0.041single-crystal X-ray studyT = 100 KwR factor = 0.118
