Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Ruthenium(IV) tetrachloride is volatile inorganic compound of ruthenium and chlorine with the formula RuCl4.[1][2]

Synthesis

Synthesis of ruthenium(IV) tetrachloride is formed by the action of chlorine gas on ruthenium(III) chloride at 750 °C:

RuCl3 + 0.5Cl2 → RuCl4

The RuCl4 is collected on a liquefied air cooled condenser and decomposes above -30 °C.[1] The reaction was determined to have the following thermodynamic properties:

The degree signs indicate standard state.

Properties

Ruthenium(IV) tetrachloride decomposes above -30 °C:[3]

RuCl4 → RuCl3 + 0.5Cl2
