Geometries and relative energies of the lowest singlet and triplet states of disilene and sllylsilylene have been investigated using ab initio SCF and CI methods. At the most reliable level of theory employed, singlet disdene is predicted to be S-10 kcal/mol more stable than singlet silylsilylene.

## Abstract Chemical bonding in the isomers of the formally triply bonded Si~2~H~2~ system are studied from the point of view of electron localization function (ELF) bond basin populations and atoms‐inmolecules (AIM) delocalization indices.

Si6H6( g) is treated as an equilibrium mixture of three isomers using recent advanced ab initio data. It is shown that equimolarity of hexasilaprismane with hexasilabenzene (lying 41 kJ/mol higher in potential energy) is reached at a temperature of 340 K while the third isomer (hexasila-Dewar benzen

The three title compounds are found to form stable negatively charged states. Si2H2 exhibits two anion states (2A s and 2Bs) corresponding to adiabatic electron affinities (EAs) of 1.76 and 1.23 eV. Si2H3 has two stable anion states ( tA and 3A) associated with EAs of 2.20 and I. 17 eV. Disilene sho

Evaporation of silicon and consecutive cocondensation of the isolation of three new C 2 H 4 Si isomers [apart from the known silacyclopropene (7) and silylacetylene (8)], namely generated atoms with acetylene or ethylene in an argon matrix turnes out to be a new access to C 2 H 2 Si and C 2 H 4 Si s
