چکیده
In the title compound, C(20)H(13)ClN(2)O(2)S, the chloro-phenyl, phenyl and thienoyl rings are oriented at dihedral angles 17.84 (7), 53.13 (8) and 34.03 (8)°, respectively, to the central pyrazole ring. An intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, pairs of bifurcated O-H⋯O hydrogen bonds link mol-ecules into inversion dimers with R(2) (2)(12) graph-set motifs.
