Figure 9
t-plot of the octahedral (upper panel) and cuboctahedral (bottom panel) distortion parameters for the refined (Pb,Bi)1 − xFe1 + xO3 − y structures. Evolution of the (Pb,Bi) coordination environment in the perovskite blocks on going from the centre to the CS planes is schematically illustrated with the corresponding structural fragments.
