Osmium(V) chloride is an inorganic chemical compound of osmium metal and chlorine with the chemical formula OsCl
5.[3][4]
Potential synthesis
Osmium(V) chloride can be obtained in small amounts by reacting osmium hexafluoride with excess boron trichloride:[5]
- 2OsF
6 + 4BCl
3 → 2OsCl
5 + 4BF
3 + Cl
2
- 2OsF
It can also be obtained by the action of sulfur dichloride on osmium tetroxide:[2]
- 2OsO
4 + 8SCl
2 + 5Cl
2 → 2OsCl
5 + 8SOCl
2
- 2OsO
Physical properties
Osmium(V) chloride forms a black dimeric solid, isomorphic with rhenium(V) chloride. OsCl
5 is sparingly soluble in non-polar solvents.[2] It is soluble in POCl3 to form a red-brown solution, which can crystallize OsCl5·POCl3.[6]
