In the crystals of the title compounds, C₈H₁₆N₂S₄, (I), and C₁₀H₂₀N₂S₄, (II), the molecules lie about inversion centres. In both structures, the C=S bonds in the two dithiocarbamate units are oriented trans to each other. In (I), the ethylene bridge and the bridged S atoms adopt a trans planar conformation and form a dihedral angle of 84.4 (2) ° with the dimethyldithiocarbamate plane. The molecule of (II) is nearly planar; in the crystal, the molecules are arranged in sheets which are stacked, 3.874 (2) A apart, parallel to (206) planes.
