In the title compound, [CoCl(2)(C(10)H(8)N(2)S)(2)](n), the Co(II) atom is located on an inversion centre and is six-coordinated by four N atoms of four symmetry-related di-4-pyridyl sulfide ligands, and two Cl atoms in trans positions, in a distorted octa-hedral geometry. The bridging bidentate di-4-pyridyl sulfide ligands link the Co(II) centres into a three-dimensional network. The four coordinating pyridine groups are donors and acceptors (N atoms) for intra-molecular C-H⋯N and C-H⋯Cl hydrogen bonds.
