Coupled Li 1+ /Nb 5+ and O 2- /F - ordering on the Na and Cl sites of the average NaCl structure of Li 4 NbO 4 F

Noren, Lasse; Withers, Raymond; Goossens, Darren; Elcombe, Margaret M; Kearley, Gordon


The average, as well as the cation and anion 'disordered', crystal structure of Li4NbO4F has been carefully investigated via coupled neutron and X-ray powder diffraction studies as well as via electron diffraction studies. The existence of a spectacular highly structured diffuse intensity distribution in the latter provides strong evidence for coupled Li1+/Nb5+ and O2-/F- ordering on the Na and Cl sites of the average NaCl structure of Li4NbO4F. Bond valence sum calculations have been used to...[Show more]
