“…The crystal structures of several other dithietanes [54][55][56] suggest interactions analogous to those described above, between negative sites and positive regions that are strongest between the extensions of the C-S and S-C bonds, so that the interaction cannot be attributed definitively to either the carbon or the sulfur. The presence of such positive regions was verified by electrostatic potential calculations in the case of tetrafluoro-1,3-dithietane, 10.…”

Close contacts and noncovalent interactions in crystals

Close contacts, defined as interatomic separations less than the sum of the respective van der Waals radii, are commonly invoked to identify attractive nonbonded interactions in crystal lattices. While this is often effective, it can also be misleading because (a) there are significant uncertainties associated with van der Waals radii, and (b) it may not be valid to attribute the interactions solely to specific pairs of atoms. The interactions within crystal lattices are Coulombic, and the strongest positive and/or negative regions do not always correspond to the positions of atoms; they are sometimes located between atoms. Examples of both types are given and discussed, focusing in particular upon σ-hole interactions.

Structural chemistry of organically-templated metal fluorides

We present a systematic survey of the structural chemistry of crystalline hybrid fluorides. About a hundred different metal fluoride building units are represented in these systems, predominantly as anionic moieties, ranging from simple tetrahedral or octahedral dimers to larger oligomeric species, complex chains, layers and, ultimately, three-dimensional frameworks. Although a few compositional spaces have been moderately well explored and certain key features of their chemistries are understood, the underlying message is that this is an area still in its infancy, ripe for further and wider exploration, rich in new crystal-chemical characteristics and, perhaps, with great potential for the development of new physical and chemical functionalities.

“…It is worth mentioning that neither the signal for the fluorinated carbocation (A) ( ca. 23 ppm) 30 nor the corresponding signal for the acyl fluoride (C) ( ca. 17.7 ppm) 31 or any other intermediates were detected in the 19 F{ 1 H} NMR experiments.…”
