Zn-Cu3(HHTP)2 chemistry. a Schematic illustration of the rechargeable Zn-2D MOF cell. b Structure of Cu3(HHTP)2, which when viewed down the c axis, exhibits slipped-parallel stacking of 2D sheets with a honeycomb lattice. The cyan, red, and gray spheres represent Cu, O, and C atoms, respectively. The H atoms are omitted for the sake of clarity. c Expected redox process in the coordination unit of Cu3(HHTP)2
