The hydrogen bond (HB) basicity of a series of ylides containing nitrogen, oxygen, or carbon as heavy atoms, as well as the influence of the formation of the HB complexes on their structure, has been studied. In addition, in this paper we propose the formation of some rather strong HBs (that could be considered low-barrier hydrogen bonds, LBHBs) between ylides and different neutral molecules. The ylides chosen for the study were H3N+−N-H, Me3N+−N-H, H2O+−N-H, Me2O+−N-H, H2O+−O-, Me2O+−O-, and… 

σ-Hole bond versus hydrogen bond: from tetravalent to pentavalent N, P, and as atoms.

The natural bond orbital method as well as the Quantum Theory of "Atoms in Molecules" is applied to characterize interactions in the analyzed complexes and it is justified that mechanisms of the formation of the Z⋅Ⓜ⓽N interactions are similar to the processes occurring for the other noncovalent links.

Hydrogen Bond versus Halogen Bond in HXOn (X = F, Cl, Br, and I) Complexes with Lewis Bases

We have theoretically studied the formation of hydrogen-bonded (HB) and halogen-bonded (XB) complexes of halogen oxoacids (HXOn) with Lewis bases (NH3 and Cl−) at the CCSD(T)/CBS//RIMP2/aug-cc-pVTZ

The boron-boron single bond in diborane(4) as a non-classical electron donor for hydrogen bonding.

The SAPT2 energy decomposition analysis shows that the relative importance of the various terms that contribute to the interaction energy depends on the strength of the interaction.

Hydrogen vs. Halogen Bonds in 1-Halo-Closo-Carboranes

A theoretical study of the hydrogen bond (HB) and halogen bond (XB) complexes between 1-halo-closo-carboranes and hydrogen cyanide (NCH) as HB and XB probe has been carried out at the MP2

Theoretical study of the Si–H group as potential hydrogen bond donor

The ability of the Si–H group as hydrogen bond (HB) donor has been studied theoretically. Most of the selected molecules include the Si–H group in a polar environment that could produce an electron

Can 2‐acylpyrroles form an intramolecular hydrogen bond?

The formation of intramolecular hydrogen bonding by certain N-substituted 2-acylpyrroles has been demonstrated by B3LYP/aug-cc-pVDZ calculations, the quantum theory of atoms in molecules, and the

Theoretical Aspects of Nonconventional Hydrogen Bonds in the Complexes of Aldehydes and Hydrogen Chalcogenides.

The stability and classification of nonconventional H-bonds including Csp2-H)...Se/Te, Te-H...Te, and Se/Te-H…O have been established for the first time.
