Osmium(III) chloride is an inorganic chemical compound of osmium metal and chlorine with the chemical formula OsCl3.[1][2]
Synthesis
[edit]Osmium(III) chloride can be made by a reaction of chlorine with osmium:
- 2Os + 3Cl2 → 2OsCl3
It can also be made by heating of osmium(IV) chloride:
- 2OsCl4 → 2OsCl3 + Cl2
Physical properties
