Because of their interesting structures and bonding and potentials as motifs for new
nanomaterials, size-selected boron clusters have received tremendous interest in recent …

In the last decades, experimental techniques in conjunction with theoretical analyses have
revealed the surprising structural diversity of boron clusters. Although the 2D to 3D transition …

Photoelectron spectroscopy (PES) in combination with computational chemistry has been
used systematically over the past decade to elucidate the structures and chemical bonding …

The idea of planar tetracoordinate carbon (ptC) was considered implausible for a hundred
years after 1874. Examples of ptC were then predicted computationally and realized …

We have investigated the structural and electronic properties of the B 17− and B 18− clusters
using photoelectron spectroscopy (PES) and ab initio calculations. The adiabatic electron …

Atomic clusters have intermediate properties between that of individual atoms and bulk
solids, which provide fertile ground for the discovery of new molecules and novel chemical …

Conspectus With three valence electrons and four valence orbitals, boron (2s22p1) is an
electron-deficient element, resulting in interesting chemical bonding and structures in both …

Transition-metal (TM)-doped boron clusters have received considerable attention in recent
years, in part, because of their remarkable size-dependent structural and electronic …

Clusters of boron atoms exhibit intriguing size-dependent structures and chemical bonding
that are different from bulk boron and may lead to new boron-based nanostructures. We …

Coordination number is one of the most fundamental characteristics of molecular structures.
Molecules with high coordination numbers often violate the octet and the 18 electron rules …
