A disilyne is a chemical compound that contains a formal silicon - silicon triple bond and as such is formulated R2Si2 (where R is a substituent group) and is the silicon analogue of an alkyne. The hypothetical parent hydride, Si2H2 does not actually exist, all attempts to synthesize it results in a diradical disilene, with the systematic name of disilene-1,2-diyl. This compound readily tautomerises to disilenylidene. Some chemists use the term silyne to refer to compounds containing a silicon-silicon triple bond whilst others use the term to refer to compounds containing a silicon-carbon triple bond by analogy to silene which often refers to compounds containing silicon- carbon double bonds. The term polysilyne can refer to the layer polymer (SiH)n or substituted derivatives.
