Figure 2. The minimal building block library of [P8W48O184]40−(abbreviated as {P8W48}) nodes and transition metal linkers (Co, Mn, Ni, Ag) that forms a family of 14 POM-all inorganic framework architectures (namelly ”POMzites”). They all share the {P8W48} building-block, with simplified ring representation green and have the four structural assembly types: chain (POMzite-4, 9,10, 14), column (POMzite-5, 6, 8, 11, 13), herringbone (POMzite-2, 7, 12) and cube (POMzite-3). We have selected 10 representative examples of the 14 POMzite architectures. To date, the explored experimental dataset consists of 30 POMzite frameworks, but the accessible chemical space is vast.
