2-[1-(2-Hy­droxy-6-meth­oxy­phen­yl)ethyl­idene]-N-methyl­hydrazinecarbothio­amide acetonitrile monosolvate

In the title compound, C₁₁H₁₅N₃O₂S·C₂H₃N, the dihedral angle between the benzene ring and the mean plane of the hydrazinecarbothio­amide group is 75.1 (2)°. In the crystal, the main mol­ecule is linked to the solvent mol­ecule by a weak N—H...N hydrogen bond while O—H...S hydrogen bonds link the mol­ecules into columns along [100].
