Crystal structure of 3-[(E)-(2-hy­droxy-3-meth­oxy­benzyl­idene)amino]-1-methyl-1-phenyl­thio­urea

In the asymmetric unit of the title compound, C(16)H(17)N(3)O(2)S, there are two independent mol­ecules (A and B), which show an E conformation with respect to the C=N bond. An intra­molecular O—H⋯N hydrogen bond with an S(6) motif stabilizes the mol­ecular structure. The terminal phenyl and benzene rings are almost orthogonal to each other, the dihedral angle being 87.47 (13)° for mol­ecule A and 89.86 (17)° for mol­ecule B. In the crystal, weak bifurcated N—H⋯(O,O) hydrogen bonds link the two independent mol­ecules, forming a supra­molecular chain with a C (2) (1)(14)[R (2) (1)(5)] motif along the b axis. A weak C—H⋯O inter­action is also observed in the chain.
