In the title compound, (C(16)H(36)N)(2)[Co(C(4)N(2)S(2))(2)](2), pairs of [Co(C(4)N(2)S(2))(2)](-) anions combine to form discrete crystallographically centrosymmetric dimers, which stack along the c axis, surrounded by the counter-cations. The metal atom in the anion has a five-coordinate distorted square-pyramidal geometry.
