Crystal structure of 3-[(E)-(2-hy-droxy-3-meth-oxy-benzyl-idene)amino]-1-methyl-1-phenyl-thio-urea.

In the asymmetric unit of the title compound, C16H17N3O2S, there are two independent mol-ecules (A and B), which show an E conformation with respect to the C=N bond. An intra-molecular O-H⋯N hydrogen bond with an S(6) motif stabilizes the mol-ecular structure. The terminal phenyl and benzene rings are almost orthogonal to each other, the dihedral angle being 87.
