In F–H–F –, a fluorine anion forms a hydrogen bond with the hydrogen in a covalent HF molecule. The spectra revealed the many states in which this ion exists in solution, which depend in ...

which causes hydrogen and fluorine atoms to form hydrogen bonds in the liquid phase. 1 The other hydrogen halides are connected by much weaker van der Waals forces. The molecule HF is commonly called ...

In this work, the team co-grafted catalytically active Co(salen) units and proximal pyridyl-substituted alkyl carboxylic acids (X-PyC n) onto Hf-based ... via hydrogen-bonding interaction, greatly ...

Ammonia (NH 3) and hydrogen fluoride (HF) both also have higher boiling points than might be predicted due to presence of hydrogen bonding between the molecules.

By designing and tuning the hydrogen-bonding microenvironment around catalytic sites ... units and pyridyl-substituted alkyl carboxylic acids (X-PyCn) onto Hf-based MOF nanosheets (MOFNs) using a post ...
