(E)-2-[(E)-3-(Hydroxyimino)butan-2-ylidene]-N-methylhydrazinecarbothioamide

In the title compound, C6H12N4OS, an intramolecular N—H⋯N hydrogen-bond is present giving rise to an S(5) ring motif. In the crystal, double-stranded chains propagating along [10] are formed via pairs of O—H⋯S and N—H⋯S hydrogen bonds. The chains are further stabilized by C—H⋯S interactions.
