The iron-based tetraoxolene honeycomb-layered compound was utilized as a cathode material for lithium-ion batteries, showing a charge-cycling performance with specific oxidation-reduction reactions and generation of radicals affecting the magnetic phase transition temperature.
The iron-based tetraoxolene honeycomb-layered compound (NPr4)(2)[Fe-2(Cl(2)An)(3)] (1; NPr4+ = tetrapropylammonium cation; Cl(2)An(2)(-) = 2,5-dichloro-3,6-dihydroxy-1,4-benzoquinonate) was used as the cathode material for lithium-ion batteries. We observed a charge-cycling performance (similar to 16 times) with three electrons/Li+ ion insertion and extraction, corresponding to the stoichiometry redox of Cl(2)An(2-) + e(-) <-> Cl(2)An(.3-) and Fe3+ + e(-) <-> Fe2+. The generation/annihilation of radicals, Cl(2)An(.3-), enables the significant improvement/deterioration of the magnetic phase transition temperature with T-c = 100 K.
