Abstract: The title compound, C₁₆H₁₈N₄S₂, has a crystallographic inversion centre at the mid-point of the central C-C bond. The plane of the dithiooxamide fragment is approximately perpendicular to the plane of the dimethylene bridge [dihedral angle = 84.8 (1)°], the plane of which is in turn normal to the pyridine ring plane [dihedral angle = 89.80 (8)°]. An intermolecular N-HN hydrogen bond involving the amide NH group and the pyridine N atom [NN = 3.0503 (18) Å and N-HN = 145.8 (14)°] links the molecules into chains extending along the c axis.
