چکیده
The mol-ecule of the title compound, C(12)H(15)N(3)O(2)S, which belongs to the family of thio-semicarbazones, containing an acid group, adopts a semi-closed conformation with an intramolecular N-H⋯N hydrogen bond. In the crystal, molecules are linked by strong N-H⋯O and O-H⋯S hydrogen bonds between the acid group and thiosemicarbazone unit, with one additional intermolecular hydrogen C-H⋯O interaction. These three interactions form R(2) (2)(8) and a R(2) (1)(7) rings and the molecules related by the c-glide plane are linked into a zigzag chain along [001].
