Halogen bonding and host-guest chemistry between
2019
Single crystal X-ray structures of halogen-bonded assemblies formed between host N-hexylammonium resorcinarene bromide (1) or N-cyclohexylammonium resorcinarene chloride (2), and 1,4-diiodooctafluorobutane and accompanying small solvent guests (methanol, acetonitrile and water) are presented. The guests’ inclusion affects the geometry of the cavity of the receptors 1 and 2, while the divalent halogen bond donor 1,4-diiodooctafluorobutane determines the overall nature of the halogen bond assembly. The crystal lattice of 1 contains two structurally different dimeric assemblies A and B, formally resulting in the mixture of a capsular dimer and a dimeric pseudo-capsule. 1H and 19F NMR analyses …
A magnetic look into the protecting layer of Au
2016
We prepared four structurally related paramagnetic Au25(SR)018 clusters. 1H ENDOR and NMR signals could be successfully related to the types of ligand and the distance of protons from the central gold core. It is shown that the unpaired electron can be used as a very precise probe of the structure of the interface between metal core and capping ligands.
