1 Chemical Bonding of Main-Group Elements

  title={1 Chemical Bonding of Main-Group Elements},
  author={Martin Kaupp},
Prior to any meaningful discussion of bonding in main-group chemistry, we have to provide a reasonably accurate definition of what a main-group element is. In general, we assume that main-group elements are those that essentially use only their valence s- and p-orbitals for chemical bonding. This leads to a number of borderline cases that require closer inspection. Assuming that the outer d-orbitals, that is, those with principal quantum number n equal to the period in question, are not true…

Exploring the role of the 3-center-4-electron bond in hypervalent λ(3)-iodanes using the methodology of domain averaged Fermi holes.
It is shown that the DAFH analysis offers a more complete understanding of hypervalency in λ(3)-iodanes, and that it is a tool to assist the search for novel reagents.
Designing M-bond (X-M···Y, M = transition metal): σ-hole and radial density distribution
Following the ubiquitous H-bond, there is a growing interest in weak non-covalent interactions involving other elements, viz., the Z-bonds (X-Z···Y, Z = halogens, chalcogens, etc.). Although almost
Gilbert Lewis and the Model of Dative Bonding
The electron-pair bonding model that was introduced by Gilbert Lewis 100 years ago is discussed in the light of modern quantum chemical methods for analysing the electronic structures of some simple
Electronegativity Seen as the Ground-State Average Valence Electron Binding Energy.
A new electronegativity scale for atoms, based consistently on ground-state energies of valence electrons, is introduced, closely related to (yet different from) L. C. Allen's, which is based on configuration energies.
Low Oxidation State Heavy P-Block Metal Compounds Supported by Di(amido) Chelating Ligands
The work presented in this thesis describes the synthesis and stabilisation of heavy p-block elements (defined herein as being those with 5s/p and 6s/p valence electrons) in low oxidation states
Physical origin of chemical periodicities in the system of elements
Abstract The Periodic Law, one of the great discoveries in human history, is magnificent in the art of chemistry. Different arrangements of chemical elements in differently shaped Periodic Tables
High Lewis Acidity at Planar, Trivalent, and Neutral Bismuth Centers
Geometric perturbation away from classical structures can engender unusual frontier MO situations leading to high Lewis acidity. Recently we reported a T-shaped bismuth triamide, which exhibited pl...


Chemical Bonding in Higher Main Group Elements
Many concepts used for a qualitative description of chemical bonding that originated in the early days of theoretical chemistry have been vindicated recently by quantum chemical calculations, at
Valence and extra‐valence orbitals in main group and transition metal bonding
Comparisons show how the divisive issue of “valence shell expansion” in transition metal bonding is deeply linked to competing conceptual models of hypervalency, and provides a quantitative measure of superiority both for the standard NAO evaluation of atomic charges as well as the general 3c/4e picture of main‐ and transition‐group hypervalence.
Charge-shift bonding and its manifestations in chemistry.
This work shows that alongside the two classical covalent and ionic bond families, there exists a class of charge-shift bonds wherein the electron-pair fluctuation has the dominant role, and outlines new directions demonstrating the portability of the new concept.
The role of radial nodes of atomic orbitals for chemical bonding and the periodic table
The role of radial nodes, or of their absence, in valence orbitals for chemical bonding and periodic trends is discussed from a unified viewpoint. In particular, we emphasize the special role of the
The Chemistry of Hypervalent Molecules
Molecules formed from atoms of Groups V–VIII of the periodic table in their higher valences are studied and a general theory for their electronic and geometric structure is presented. These
On the Relation between π Bonding, Electronegativity, and Bond Angles in High‐Valent Transition Metal Complexes
Bonding modelsfor d0complexes are invariably more complicated than for main group compounds due to the complicated dependence of in-plane and out-of-plane π-components on bond angles in the former.
"Non-VSEPR" Structures and Bonding in d(0) Systems.
This work attempts to provide a comprehensive view, both of the types of deviations of d(0) and related complexes from regular coordination arrangements, and of the theoretical framework that allows their rationalization.
Relation between singlet-triplet gaps and bond energies
shortened (strengthened). The parenthetical equivalents are justified because of the well-established correlation between bond length and bond strength. Indeed, the lower interaction energy for the H
