The generation of the paramagnetic radical (Cl2An[rad]3−) in the framework-edge moieties of an Fe-based two-dimensional honeycomb framework with 2,5-dichloro-3,6-dihydroxy-1,4-benzoquinonate (Cl2Ann ), (H3O)2(phz)3[Fe2(Cl2An)3] (phz = phenazine), allowed the formation of long-range magnetic correlations over the network with a relative high magnetic phase transition temperature (Tc) of 128 K. The original compound is a paramagnet with a diamagnetic Cl2An2− linker that significantly separates paramagnetic FeII ions (S = 2), where the [(H3O)2(phz)3]2+ cation is located between layered frameworks. Post-synthetic electron-doping, i.e., reduction in the solid state, using a lithium-ion battery (LIB) system, finally produced (Li+)3(H3O+)2(phz)3[(Fe2+)2(Cl2An[rad]3−)3], which demonstrated a drastic magnetic change.
