N-[(5-Chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)carbonyl]-N′-(4-hydroxyphenyl)thiourea

In the title compound, C18H15ClN4O2S, the pyrazole ring makes dihedral angles of 67.4 (1) and 12.5 (1)° with the phenyl and 4-hydroxyphenyl groups, respectively; the two benzene rings are twisted by 60.1 (1)° with respect to each other. The thiourea NH groups are involved in N—H...O and N—H...Cl intramolecular hydrogen bonds. A hydrogen bond between the phenolic OH group and the pyrazole N atom connects molecules into a one-dimensional polymeric structure.
