Halogen bonding as a supramolecular dynamics catalyst

open access: yesNature Communications, 2019
The halogen bond is well known for its ability to assemble supramolecules. Here, using NMR experiments, the authors reveal the role of these bonds in dynamic processes, finding that the halogen bond directly catalyzes dynamical rotation in solid ...

Crystal structure of (Z)-2-fluorobenzyl 2-(5-fluoro-2-oxoindolin-3-ylidene)hydrazinecarbodithioate dimethyl sulfoxide monosolvate

open access: yesActa Crystallographica Section E: Crystallographic Communications
The title solvate, C16H11F2N3OS2·C2H6OS, crystallized with two independent molecules (A and B) in the asymmetric unit. Both molecules exhibit an L-shaped geometry but slightly differ in the orientation of the o-fluorobenzyl ring with respect to the 5 ...

The Influence of Liquid on the Outcome of Halogen-Bonded Metal–Organic Materials Synthesis by Liquid Assisted Grinding

open access: yesCrystals, 2017
In this work, we describe novel multi-component halogen bonded solids of Co(ii) complexes and 1,4-diiodotetrafluorobenzene, 14tfib. We present the important influence of liquid on the outcome of liquid assisted grinding of dichlorobis(1,10-phenantroline ...

Halogen-Bonded Supramolecular Parallelograms: From Self-Complementary Iodoalkyne Halogen-Bonded Dimers to 1:1 and 2:2 Iodoalkyne Halogen-Bonded Cocrystals

open access: yes
The formation of supramolecular parallelograms utilizing iodoalkyne–pyridine halogen bonding is described. The crystal structures of four iodoalkynyl-substituted (phenylethynyl)pyridines demonstrate the feasibility of discrete self-complementary dimer ...
