A route for systematically accessing the oxo atoms of linear uranyl (UO22+) cation via cation–cation and halogen bonding interactions is detailed, interaction strengths are probed structural, vibrational, computational means.

Halogen bonds (XBs) are noncovalent interactions where halogen atoms act as electrophilic species interacting with Lewis bases. These relevant in biochemical systems being increasingly explored drug discovery, mainly to modulate protein–ligand interactions, but also found engineered protein or nucleic acid systems. In this work, we report direct evidence for the existence of XBs context biologi...

Abstract The hydrogen bonding in the Au(I) complex [Au(F ⋅ HF)(SPhos)] (SPhos=dicyclohexyl(2’,6’‐dimethoxy[1,1’‐biphenyl]‐2‐yl)phosphane) ( 1 a HF) has been analysed by IR and NMR measurements, revealing formation of an unsymmetrical bifluoride moiety. data are excellent agreement with DFT calculations. Comparisons to analogous complexes bearing NHC (NHC= N ‐heterocyclic carbene) ligands demons...
