In the crystal structure of the centrosymmetric binuclear title complex, [Ni₂(C₁₂H₈N₂O₂S)₂(CH₃OH)₄], there are intermolecular O-HO, O-HN and O-HS hydrogen bonds. These help to stabilize the structure and link the molecules, forming a three-dimensional network structure. The Ni²⁺ cation exists in a slightly distorted octahedral NiNO₅ coordination environment. The thiophene rings are disordered over two equivalent conformations with occupancies of 0.881 (3) and 0.119 (3).
