Thermolysis of the dithiocarbamate complex 1 led to the formation of the thiocarbenoid complex 2 and two double cubanes: 3 , which has an intercubane Cr−Cr bond and a dithiooxamide ligand in the μ ‐ η 2 , η 4 bonding mode, and 4 , which contains two dithiocarbamate ligands in the μ ‐ η 1 , η 2 bonding mode.
