Synthesis
Ruthenium(II) chloride can be prepared by reacting ruthenium metal with dry chlorine at 250 °C:[2]
- Ru + Cl2 → RuCl2
It can also be prepared by treating a ruthenium trichloride solution with hydrogen in the presence of platinum black:[1]
- 2RuCl3 + H2 → 2RuCl2 + 2HCl
Reactions
Ruthenium(II) chloride forms complexes with aromatic hydrocarbons.[3]
The compound can be reduced to elemental ruthenium by hydrogen.
