An unusual O 2− /F − distribution in the new pyrochlore oxyfluorides: Na 2 B 2 O 5 F 2 (B = Nb, Ta)

Abstract

Two new oxyfluorides with a pyrochlore-type structure, Na 2 Nb 2 O 5 F 2 and Na 2 Ta 2 O 5 F 2 , have been obtained, and for which the XRD crystallographic study coupled with 19 F solid state NMR reveals an unusual O/F distribution.
