FIG. 5.

Modified local structure of J14 and J35. Illustration depicting local structural changes about the cobalt species in (a) J14 and (b) J35. A comparison of the changes as a result of adding the 6th cation can be viewed by unit cell cross section along the (200) plane, as shown in (c) and (d) for J14 and J35 respectively. The lowercase roman numerals mark the coordination shell radius for i. nearest neighbor anion, ii. next nearest neighbor anion, and iii. nearest neighbor cation. In both cases, the nearest neighbor cation shell radius corresponds to one-half the face diagonal of the unit cell parameters, as determined through XRD.
