2-[1-(2-Hydroxy-4-methoxyphenyl)ethylidene]-N-methylhydrazinecarbothioamide

In the title compound, C11H15N3O2S, the dihedral angle between the mean planes of the benzene ring and hydrazinecarbothioamide group is 9.2 (1)°. An intramolecular O—H...N hydrogen bond is observed, serving to maintain an approximately planar conformation for the molecule. In the crystal, inversion dimers linked by C—H...O interactions occur. Further C—H...O contacts link dimers into (010) chains
