In the title compound, [Zn(C(8)H(8)N(3)S(2))(2)], the Zn atom is coordinated by the two ligands in a tridentate manner, via the pyridyl N, the azomethine N and the thiol-ate S atom; the coordination geometry is distorted octa-hedral, with the two ligands in the mer configuration (two S atoms and two pyridyl N atoms are cis with respect to each other and the azomethine N atoms is trans). The mol-ecules are linked by C-H⋯S hydrogen bonds, forming a three-dimensional network structure.
