Silico-acetylene, (Si2H2)n

Silico-acetylene, (Si2H2)n, was prepared by Bradley by decomposing calcium silicide with hydrochloric acid:

CaSi2 + 2HCl = CaCl2 + Si2H2.

It is a yellow crystalline substance, showing no resemblance to acetylene, and is undoubtedly polymerised.

The following table shows the boiling- and melting-points of the three hydrides of silicon, together with those of the corresponding hydrocarbons. The difference in boiling-point between ethane and silico-ethane is particularly noteworthy.
