Correlations along the CO3 chains of Ba3Co2O6(CO3)0.7 with the A′ molecule variant located at the origin: (a) occupancy, (b) displacement and (c) vacant–displacement pairs. The chain pair correlations follow the A′–A–B order illustrated in (d), the relative unit-cell fractional coordinates and the distance between variants. Representing the molecules as atoms, (e) an illustration of chain disorder is shown with displaced molecules (hatch fill) moving away from their average position (blue fill) toward nearby vacant sites (pink fill) along the chain.
