Interstitial oxygen atoms ( δ ), identified by difference Fourier maps from NPD data, enhance the conductivity of La 1.2 Sr 0.8 InO 4.11 , with an extremely low activation energy of only 0.51 eV for the conduction mechanism of O 2− at low temperatures.

H 2 O molecules are split within the structure with protons bonded to the axial oxygens of the InO 6 octahedra, and with OH units occupying the interstitial space.
