title: 1-(4-tert-Butyl-benz-yl)-3-phenyl-1H-pyrazole-5-carboxylic acid.
abstract: In the title compound, C(21)H(22)N(2)O(2), the mean plane of the pyrazole ring makes dihedral angles of 18.80 (12) and 77.13 (5)°, respectively, with the mean planes of the phenyl and tert-butyl-benzyl rings. The carboxylate group is inclined at 8.51 (14)° with respect to the pyrazole ring. The crystal structure displays inter-molecular O-H⋯O hydrogen bonding, generating centrosymmetric dimers.
