Ethenedithione can exist as a gas at low pressure and high temperature, but is unstable when condensed or under higher pressure.

It can be stabilized as a ligand binding two cobalt atoms.

Other occurrences as a ligand are in TpW(CO)2(C2S2) and [TpW(CO)2]2Ni(C2S2)2, where Tp is trispyrazolylborate.
