Hexachlorodisiloxane

Template:Chembox 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: Failed to parse (syntax error): {\displaystyle \ce{2SiCl4{} + O2 ->[\atop{950-970\,^\circ\text{C}}] 2(SiCl3)2O{} + Cl2}}

At room temperature, it is a colorless liquid that hydrolyzes upon exposure to water to give silicon dioxide and hydrochloric acid: $$(\mathrm{S}\mathrm{i}\mathrm{C}\mathrm{l}{\phantom{A}}_3){\phantom{A}}_2\mathrm{O}+3\mathrm{H}{\phantom{A}}_2\mathrm{O}⟶2\mathrm{S}\mathrm{i}\mathrm{O}{\phantom{A}}_2+6\mathrm{H}\mathrm{C}\mathrm{l}$$ Intense heat evinces a similar decomposition: Failed to parse (syntax error): {\displaystyle \ce{2(SiCl3)2O ->[\atop{\Delta}] SiO2{} + 3SiCl4}}

Reaction with antimony trifluoride gives the analogous hexafluorodisiloxane.
