Synthesis

Synthesis of ruthenium(IV) tetrachloride is by action of hydrogen chloride on ruthenium(VIII) oxide:

RuO4 + 8HCl → RuCl4 + 2Cl2 + 4H2O

Physical properties

Ruthenium(IV) chloride forms brown hygroscopic crystals.

Ruthenium(IV) tetrachloride forms a hydrate of the composition RuCl4·5H2O.

The compound dissolves in cold water and ethanol.

Chemical properties

Ruthenium(IV) tetrachloride decomposes when heated in an inert atmosphere:

RuCl4 → Ru + 2Cl2

Ruthenium(IV) tetrachloride decomposes in hot water:

RuCl4 + H2O → [Ru(OH)Cl3] + HCl

When heated, the compound is oxidized by oxygen in the air:

RuCl4 + O2 → RuO2 + 2Cl2

Uses

Ruthenium tetrachloride is used in chemical reactions as a strong oxidant.[5]
