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.
