Description:

(abstract)

Herein, we quantitatively determined the Mo/Nb order in the high ion conductor Ba7Nb4MoO20 by a novel technique combining of resonant X-ray diffraction, solid-state nuclear magnetic resonance (NMR) and first-principle calculations. NMR provided direct evidence that Nb and Mo atoms occupy three and only M2 sites, respectively, where the M2 site is located near the intrinsically oxygen-deficient ion-conducting layer.
