To estimate the lattice energies for KMnO4 and Kcrypt222MnO4 we can make use of the BornHaber cycle and the formulas provided in Table 66 However these formulas generally apply to simple ionic solids ...

Cryptands such as crypt-[222] (see Fig. 11.9) are encapsulating ligands for s-block metal ions. Use the VBT

Question:

Cryptands such as crypt-[222] (see Fig. 11.9) are encapsulating ligands for s-block metal ions. Use the VBT approach to estimate values for the lattice energies of KMnO₄ and [K(crypt-[222])][MnO₄]. Comment on difference between the values. Data: see Tables 6.5 and 6.6; V(K(crypt-[222])⁺) = 0:531 nm³.
