The geometry at an element centre can generally be predicted based on the number of
electron pairs around it using valence shell electron pair repulsion (VSEPR) theory …

Fundamental research on germanium as the central element in compounds for bond
activation chemistry and catalysis has achieved significant feats over the last two decades …

In this feature article, an overview of the chemistry of pyramidanes, as a novel class of main
group element clusters, is given. A general introduction sets the scene, briefly presenting the …

Since the late 19th century, heavier tetrylene-and tetrylyne-transition metal chemistry has
formed an important cornerstone in both main-group and organometallic chemistry alike …

Achieving a planar hypercoordinate arrangement of s‐block metals through covalent
bonding with ligands is challenging due to the strong ionicity involved. Herein, we report the …

Photoelectron spectroscopy and theoretical calculations have identified the global minimum
structure of the 16‐valence electron Si3Cu3‐cluster, which features a planar tetracoordinate …

Diboriranides are the smallest conceivable monoanionic aromatic cycles, yet only limited
examples have been reported and their reactivity and complexation behavior remain …

As one of the important probes of chemical bonding, planar tetracoordinate carbon (ptC)
compounds have been receiving much attention. Compared with ptC clusters, the heavier …

Tetracoordinate silicon species are typically tetrahedral, weak Lewis acids, and often
sensitive to moisture. In this study, we present a tetra-amido macrocyclic ligand (TAML) …

The facile reaction of the SiPh2‐bridged bis‐silylene (LSi:) 2SiPh2 (L= PhC (NBut) 2) with
diphenylacetylene affords the unprecedented 1, 2, 3‐trisilacyclopentadiene (LSi) 2 (PhC) …
