In the presence of ionic compounds, the thermal decomposition of octacarbonyldicobalt, Co 2 (CO) 8 , in an inert solvent leads exclusively to ϵ‐Co nanocubes. The ionic species can be added directly or generated in situ by a chemical reaction between an additive and the precursor or between two additives. The additional presence of an inhomogeneous magnetic field leads to disc‐shaped crystalline nanoparticles, which assemble to chains.
