(a) Single-crystal X-ray structure of MOF-1992 based on the Fe-trimers and Co-phthalocyanine catechollinkers (CoPc). Atoms color: C-black; O-red; N-green; Co-orange; Fe-blue polyhedra. Hydrogen atoms and the chlorido ligands are omitted. The anionic charge of [Fe6(OH2)4(CoPc)3]6-, MOF-1992, was balanced by the presence of [X] n counterions (X represents Mg2+ or Fe3+). Electrochemical characterizations of the MOF-1992 (b) Cyclic voltammetry (CV) of the MOF-1992/CB (CB, carbon black). The vertical line display the potential of Co-Pc-semiquinolate (CoPc-SQ) 4-/CoPc-catecholate (CoPc-cat) 8-redox couple (c) CV of the MOF-1992/CB in a CO2-saturated (black, pH = 6.8) and N2-saturated (green, pH = 7.2) KHCO3 solution.
