【 摘 要 】

The structure of the title compound, C11H15N3OS, shows the flexibility due to the methyl­ene group at the thio­amide N atom in the side chain, resulting in the mol­ecule being non-planar. The dihedral angle between the plane of the benzene ring and that defined by the atoms of the thio­semicarbazide arm is 79.847 (4)°. In the crystal, the donor–acceptor hydrogen-bond character of the –OH group dominates the inter­molecular associations, acting as a donor in an O—H⋯S hydrogen bond, as well as being a double acceptor in a centrosymmetric cyclic bridging N—H⋯O,O′ inter­action [graph set R22(4)]. The result is a one-dimensional duplex chain structure, extending along [111]. The usual N—H⋯S hydrogen-bonding association common in thio­semicarbazone crystal structures is not observed.
