“…This then leads to multimetallic complexes where all the metal ions are in the same coordination environment. For bimetallic species, commonly‐observed coordination motifs involving dithiolene ligands include [M 2 (dithiolene) 4 ] (M = Mn,, Fe,, Co,, , Ni,, ), [M 2 (dithiolene) 5 ] (M = Mo, Rh, Re), and [M 2 (Cp) 2 (dithiolene) 2 ] (Cp = cyclopentadienyl, M = V, Cr, Fe, Co, Mo, Rh) . In such complexes, the coordination environment around one metal center is almost always the same as that around the other metal center, and this is especially true when the metals in question are drawn from the first row of the d‐block.…”

Bimetallic complexes of the transition metals containing mixed diimine and dithiolate ligands are of fundamental interest on account of their intriguing electronic properties. Almost always, such complexes are isolated as species in which both the metal centers are in identical coordination environments – this means that the two metals often have identical redox properties. In contrast, mixed‐diimine/dithiolate bimetallic complexes of the first row transition metals where the two metals are in dissimilar coordination environments are exceedingly rare, and are only known for nickel. Herein, we report the first ever example of a mixed‐diimine/dithiolate dicobalt complex where the two cobalt centers are in different coordination environments. The synthesis of this compound is straightforward, and produces a complex in which the two cobalt centers display very different redox properties.
