1,2-Bis[bis-(methyl-sulfan-yl)methyl-ene]hydrazine.

The title compound, C(6)H(12)N(2)S(4), was obtained as a by-product (8%) during the reaction of the electrogenerated cyano-methyl anion with phenyl-amine, carbon disulfide and methyl iodide. The mol-ecule, with the exception of 8 H atoms, lies on a crystallographic mirror plane and is arranged around an inversion centre located at the mid-point of the N-N bond.
