Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a free service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are accessible to all readers and citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain. ACS cannot be held responsible for errors or consequences arising from the use of information contained in these “Just Accepted” manuscripts.

Figure 2. Views of the single crystal X-ray structure of 4a (a) showing the top and bottom rings linked by axial ligands, with linkages between FeII centers (purple spheres) added in order to highlight the D4 point symmetry; (b) showing the ligands in a space-filling view down the central channel; (c) highlighting a pair of mer vertices, with the three magnetically distinct environments shown in blue, red, and green; (d) showing the placement of the ordered PF6− counterions above the -C6F4- rings. In all views the non-encapsulated anions, solvent molecules and disorder are omitted for clarity. 564x565mm (192 x 192 DPI)

Figure 4. Proportion of each species observed for (a) tetrahedron 3 and (b) tetragonal prism 4a compared to the binomial (statistical) distribution. Error bars represent the standard deviations of the amounts of each congener measured between the different charge states observed in the ESI-MS. (c) and (d) provide plots of the energy of each species relative to tetrahedron 3 in (c), containing only non-fluorinated C residues, and the tetragonal prism 4a in (d), containing only fluorinated D residues. Ert and Erp refer to the relative energies between congeners respectively in the cases of the tetrahedral series and the prismatic series. α represents the energetic destabilization per ligand exchanged. 393x262mm (192 x 192 DPI)
