Highlights with ‘bonding analysis’

Anion Binding and Transport with Aromatic Pentaamide Macrocycles

Hosts with an affinity towards specifically charged guest species are crucial for combating a variety of diseases. Synthetic supramolecular structures are designed to bind to either cations or anions. The pore of a macrocycle may...

Improving Hydrogen Evolution by Mn Doping MoS2 Nanosheets: DFT QTAIM analysis

In a recent combined experimental and theoretical paper, periodic DFT calculations and Bader’s QTAIM analysis explain, at the atomistic level, the enhancement of the performance of MoS2 2D material for the hydrogen evolution reaction (HER),...

10- and 14-Valence-Electron Triple Bond Systems: Isoelectronic Families Differing By a dδ4 Ring

Triple bonded A≡A’ 10-valence electrons (VE) main-group diatomics, such as N2, CO, CN- and NO+, have a strong σ2π4 triple bond plus a lone pair at each end. Adding four more valence electrons, as in...

On the existence of collective interactions in organometallic compounds

In a recent Nature Communications paper, extensive bonding analysis is used to dispute a previous claim on the nature of the Li-C chemical bond. This work involved Prof. Jordi Poater of the IQTCUB institute of...

Actinide-Lanthanide bonding unraveled

Metal-metal bonding is a classic research topic in chemical bonding studies and has been applied as a tool for developing molecular magnets as well as for addressing challenges in biology, energy, and catalysis. In particular,...

Relativistic effects boost the termination of the classic periodic law of chemistry for the heavy elements

Many chemistry textbooks assume the unlimited validity of a simplified Periodic Law of Elements. In Nature, the chemical periodicity of the elements results from the large energy gaps between the atomic core and valence shells...
