Negative hydration expansion in ZrW2O8: microscopic mechanism, spaghetti dynamics, and negative thermal expansion
- Abstract:
-
We use a combination of x-ray diffraction, total scattering, and quantum mechanical calculations to determine the mechanism responsible for hydration-driven contraction in ZrW2O8. The inclusion of H2O molecules within the ZrW2O8 network drives the concerted formation of new W─O bonds to give onedimensional ð─W─O─Þn strings. The topology of the ZrW2O8 network is such that there is no unique choice for the string trajectories: the same local changes in coordination can propagate with a large nu...
