The title compound, C 16 H 18 N 4 S 2 , 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 t
