3-{(E)-[1-(2-Hy-droxy-phen-yl)ethyl-idene]amino}-1-(2-methyl-phen-yl)thio-urea.

ABSTRACT: In the title thio-urea derivative, C(16)H(17)N(3)OS, the hy-droxy- and methyl-substituted benzene rings form dihedral angles of 9.62?(12) and 55.69?(6)°, respectively, with the central CN(3)S chromophore (r.m.s. deviation = 0.0117?Å). An intra-molecular O-H?N 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 supra-molecular chains sustained primarily by N-H?S hydrogen bonds are found. Additional stabilization is provided by C-H?? and ?-? [ring centroid(hy-droxy-benzene)?ring centroid(methyl-benzene) = 3.8524?(18)?Å] inter-actions.
