Abstract: In the title thiourea derivative, C₁₆H₁₇N₃OS, the hydroxy- and methyl-substituted benzene rings form dihedral angles of 9.62 (12) and 55.69 (6)°, respectively, with the central CN₃S chromophore (r.m.s. deviation = 0.0117 Å). An intramolecular O-HN hydrogen bond ensures the coplanarity of the central atoms. The H atoms of the NH groups are syn and the conformation about the N=C double bond [1.295 (4) Å] is E. In the crystal, helical supramolecular chains sustained primarily by N-HS hydrogen bonds are found. Additional stabilization is provided by C-H and - [ring centroid(hydroxybenzene)ring centroid(methylbenzene) = 3.8524 (18) Å] interactions.
