Potential synthesis
- Reaction of chlorine with osmium at 100–500 °C:
- 2Os + 3Cl2 → 2OsCl3
- Electrolysis of osmium(IV) chloride solution:
- 2OsCl4 → 2OsCl3 → Cl2
Physical properties
Osmium(III) chloride forms black-brown crystals.[3]
It dissolves well in water, dissociates to a small extent, hydrolysis by cation.
Forms a crystallohydrate of the composition OsCl
3•3H
2O — dark green crystals.[4]
Uses
Osmium(III) chloride hydrate is used as a precursor material for the production of dichlorodihydridoosmium complex compounds and other compounds.[5]
