Silicon hydrides

Disilene is an inorganic compound with the chemical formula . The name disilene, referring to the structure of a particular prototropic tautomer of the molecule. It is the simplest silene.

Disilyne is a low valent silicon compound with the chemical formula Si2R2 where oxidation state of Si is +1. Several isomers are possible, but none are sufficiently stable to be of practical value. Substituted disilynes contain a formal silicon–silicon triple bond and as such are sometimes written R2Si2 (where R is a substituent group). They are the silicon analogues of alkynes.
