Hexachlorodisiloxane is a chemical compound composed of chlorine, silicon, and oxygen.

Structurally, it is the symmetrical ether of two trichlorosilyl groups, and can be synthesized via high-temperature oxidation of silicon tetrachloride:

SiCl

SiCl

At room temperature, it is a colorless liquid that hydrolyzes upon exposure to water to give silicon dioxide and hydrochloric acid:

SiCl

Intense heat evinces a similar decomposition:

Reaction with antimony trifluoride gives the analogous hexafluorodisiloxane.
