Four bis‐ammonia ligated cobalt corroles and four mono‐DMSO ligated cobalt corroles with different meso ‐aryl substituents on the macrocycle (A 2 B‐ and A 3 ‐corroles) were synthesized and investigated as to their electrochemical and spectroscopic properties under different solution conditions. The complexation energies of the investigated cobalt corroles were theoretically calculated to illustrate the propensity of the cobalt center for penta‐coordination or hexa‐coordination with various axial ligands (DMSO, CO, py and NH 3 ). The structure of one hexacoordinate bis‐NH 3 cobalt corrole complex was also determined by X‐ray diffraction.
