چکیده
The title compound, C(15)H(20)BrN(3)O(2)S, crystallizes in the thio-amide form and adopts an E,E conformation with respect to the azomethine and hydrazinic bonds, respectively. The mol-ecules are paired through N-H⋯O and O-H⋯S hydrogen bonds, leading to the formation of centrosymmetric dimers in the crystal. These dimers are stacked along the a axis and are inter-connected through N-H⋯S hydrogen bonds to generate polymeric chains. The structure also features C-H⋯π interactions. An intra-molecular O-H⋯O bond is also present.
