Consider the PtS net listed in Table 1.6. The dehydrated form of MOF-11 has composition Cu₂(ATC) where ATC is 1,3,5,7-adamantane tetracarboxylate and contains a Cu paddle-wheel unit analogous to the Zn dimer shown in Figure 14.13. Describe the structure of PtS. Based on the information given and your chemical knowledge, suggest possible structures for MOF-11 and ZnPt(CN)₄.
