In addition, higher silanes can also be obtained by discharges monosilane:[3]
Properties
Tetrasilane is a colourless,
pyrophoric liquid that has a disgusting odour. Even below 54 °C, it will still spontaneous combust.[1] It is even more unstable than
trisilane, slowly decomposing at
room temperature, releasing hydrogen and forming shorter chain silanes.[5]
Reactions
Photochemical disproportionation of tetrasilane will produce
3-silylpentasilane and disilane.[6]
With the presence of
aluminium chloride, heating tetrasilane in
xylene will allow isomerization to isotetrasilane.[7]
