铁基四氧杂环戊烯蜂窝层状化合物（NPr 4）2[Fe 2（Cl 2An）3]（1; NPr 4 +=四丙基铵阳离子; Cl 2An 2-= 2，5-二氯-3，6-二羟基-1，4-苯醌）用作锂离子电池的阴极材料。我们观察到了三个电子/Li+离子插入和提取的充电循环性能（1016次），对应于化学计量的Cl_2An ~（2-）+e-ParticCl_2An·3 ~-和Fe ~（3+）+e-ParticFe ~（2+）的氧化还原。Cl_2An·3-自由基的产生/湮灭使Tc = 100 K的磁相变温度显著提高/降低。
The iron-based tetraoxolene honeycomb-layered compound (NPr4)2[Fe2(Cl2An)3] (1; NPr4+= tetrapropylammonium cation; Cl2An2–= 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 (∼16 times) with three electrons/Li+ion insertion and extraction, corresponding to the stoichiometry redox of Cl2An2–+ e–↔ Cl2An·3–and Fe3++ e–↔ Fe2+. The generation/annihilation of radicals, Cl2An·3–, enables the significant improvement/deterioration of the magnetic phase transition temperature withTc= 100 K.
