We present a method for approximating thermodynamic parameters , Δ H , and Δ S for the cation exchange process in metal-organic frameworks, as exemplified by Ni 2+ exchange into Zn 4 O(1,4-benzenedicarboxylate) 3 (MOF-5) and Co 2+ exchange into MOF-5 and Zn 5 Cl 4 (bis(1 H -1,2,3-triazolo-[4,5- b ],[4′,5′- i ])dibenzo-[1,4]-dioxin) 3 (MFU-4 l ). For these examples, we find that the cation exchange process is endergonic and that parameters such as solvent and cation identity impact the thermodynamics.
