Cyclopentasilane is a cyclic compound of silicon and hydrogen with the chemical formula . Containing five silicon atoms arranged in a pentagonal ring, it is the silicon analog of cyclopentane. Cyclopentasilane is a colorless pyrophoric liquid. It is an oligosilane. It is of research interest because of its potential use as a liquid silicon ink for printing silicon structures on integrated circuits or solar cells.

==Production== Cyclopentasilane can be made from diphenyldichlorosilane (C6H5)2SiCl2 reacting with lithium. This forms decaphenylcyclopentasilane. This reacts with aluminium chloride in benzene catalysed with hydrogen chloride to yield decachlorocyclopentasilane. Decachlorocyclopentasilane then has its chlorine replaced by hydrogen using lithium aluminium hydride.
