An N,N'-disubstituted dithiooxamide derivative reacts with 1,2-dibromoethane to produce the title compound, C(18)H(18)N(2)S(2), a heterocycle with a double Schiff base. In the crystal structure, the molecule of the title compound lies on a twofold axis. Weak C-H...pi interactions are the principal intermolecular forces, mediating the formation of layers parallel to the ab plane. Each molecule participates as donor and acceptor in two such contacts.
