摘要：
The structure of the non-stoichiometric pyrochlore NaW2O6 center dot nH(2)O has been refined from powder neutron diffraction data using the Rietveld method. The stoichiometry found from the structural refinements is Na0.85(2)W2.02(2)O6 center dot 0.92(5)H2O in good agreement with other analytical studies. The Na cation is seven-coordinated bonding to six framework oxygen atoms and one oxygen atom from the water. The refinements show a disordered H2O Molecule to be present with the O(2) on a 32e site and the H(1) 48f site. Crown Copyright (c) 2006 Published by Elsevier B.V. All rights reserved.
