Aromatic compounds have been known for more than 180 years, ever since the discovery by
Faraday in 1825 of the first aromatic hydrocarbon, benzene,[1] whose remarkable cyclic …

Until recently the low-coordinate compounds of the heavier elements of group 14 were
known only as transient, unstable species which were difficult to isolate. However recent …

Gold is known to be the noblest of all metals because of the relativistic stabilization of its
outer 6s orbital. The relativistic effects also lead to destabilization of the 5d orbitals, reducing …

Cyclic polyenes, such as benzene, cyclopentadienyl and cyclobutadiene, are widely used
as key ligands for a variety of transition-metal complexes. The heavy versions of these …

We have explored in detail the potential energy surfaces of the Si5Li n 5− 6 (n= 5− 7)
systems. We found that it is feasible to design three-dimensional star-like silicon structures …

The isolation and characterization of the first silicon analogue of the aromatic
cyclobutadiene dication is reported. The aromatic 2π-electron tetrasilacyclobutadiene …

A single Au atom has been shown to behave like H in its bonding to Si in several mono-and
disilicon gold clusters. In the current work, we investigate the Au∕ H analogy in trisilicon …

The geometries and stabilization energies (SE) of B3H „molecules and ions were computed
ab initio at MP2-(FULL)/6-31+ G*+ ZPE (HF/6-31+ G*). QCISD (T)/6-31 l+ G**//MP2 (FULL)/6 …

A new class of superalkali cations X 3 Li 3+(X= C, Si and Ge) containing three planar
tetracoordinate X atom have been characterized using ab initio methods. These perfect …

Despite the very high ring strain, the cyclopropenium ion (1-C) is highly stable since it
benefits from the highest resonance stabilization energy of all Huckel 4n+ 2C „H …
