(a) Radial pair distribution functions (RDFs) and (b) integral of RDFs for the interaction between Li+ and K+ and Zr(dcphOH-NDI) in DMF. Every linker in Zr(dcphOH-NDI) is reduced by one electron. The integral RDF shows the number of ions at a distance from the NDI-O; as every NDI contains four O-centers, one cation/NDI corresponds to an integral of 0.25.
