Disilyne


Disilyne, Si
2H
2, is a metalloid hydride composed of silicon and hydrogen. Disilyne is not well-characterised or well-known, and it is kinetically unstable with respect to isomerisation. The most stable isomer is a dibridged singlet, named di-μH-disilyne, followed by a monobridged μH-disilyne. A third, unbridged singlet ismomer is predicted to exist before disilyne - disilenylidene.
