Abstract: The structure of the defect pyrochlore CsTi0.5W1.5O6 has been investigated using electron, synchrotron X-ray and neutron diffraction methods. The material is cubic a = 10.2773 angstrom with displacive disorder of the Cs cations along the < 1 1 1 > direction. The local structure, revealed by the diffuse structure in the electron diffraction patterns shows there is correlated displacement of the heavy Cs atoms along the < 1 1 0 > directions. The thermal expansion of the material is also described. © 2008, Elsevier Ltd.
