Multiple boron-boron bonds in neutral molecules: an insight from the extended transition state method and the natural orbitals for chemical valence scheme.
67
TL;DR: It is concluded that use of phosphorus ligands leads to strengthening of the B═B bond by 6.4 kcal/mol, and the orbital interaction term is more stabilizing; however, the effect is less pronounced compared to the drop in the Pauli repulsion term.

Abstract: We have analyzed the character of B═B and B≡B bonds in the neutral molecules of general form: LHB═BHL (2-L) and LB≡BL (3-L), for various ancillary ligands L attached to the boron center, based on a...

TL;DR: It is reported that main group element boron is able to form quadruple bonding interactions with iron in the BFe(CO)3 - anion complex, which has been revealed by quantum chemical investigation and identified by mass-selected infrared photodissociation spectroscopy in the gas phase.
Ultrashort Beryllium-Beryllium Distances Rivalling Those of Metal-Metal Quintuple Bonds Between Transition Metals.
TL;DR: A computational design and characterization of novel main group species containing ultrashort metal-metal distances between two beryllium atoms in different molecular environments, including a rhombic Be2 X2 (X=C, N) core, a vertical Be-Be axis in a 3D molecular star, and a horizontal Be- be axis supported by N-heterocyclic carbene (NHC) ligands.

Density-functional exchange-energy approximation with correct asymptotic behavior.
TL;DR: This work reports a gradient-corrected exchange-energy functional, containing only one parameter, that fits the exact Hartree-Fock exchange energies of a wide variety of atomic systems with remarkable accuracy, surpassing the performance of previous functionals containing two parameters or more.

TL;DR: The “Activation‐strain TS interaction” (ATS) model of chemical reactivity is reviewed as a conceptual framework for understanding how activation barriers of various types of reaction mechanisms arise and how they may be controlled, for example, in organic chemistry or homogeneous catalysis.

TL;DR: In this paper, a numerical-variational computational scheme for performing self-consistent molecular MO LCAO calculations in the HFS model is presented, where the local exchange approximation is used, but the usual muffin-tin approximation for potentials or densities is avoided.
