HfW$_{2}$O$_{8}$
- Unusually, both ZrW$_{2}$O$_{8}$ and HfW$_{2}$O$_{8}$ have a negative thermal expansion over temperatures ranging from 0.3K to 693K. (Evans, 1996)
- Below ≈423K these compounds are in the low-temperature ZrW$_{2}$O$_{8}$ structure, sometimes referred to as $\alpha$–ZrW$_{2}$O$_{8}$.
- Above the transition the compounds are in this somewhat disordered high-temperature ($\beta$) ZrW$_{2}$O$_{8}$ structure.
- In this high-temperature phase all of the (8c) sites are only 50% occupied. Only one of each conjoined pair of atoms in the diagram will be present in a real sample.
