Osmium(V) chloride is an inorganic chemical compound of osmium metal and chlorine with the chemical formula OsCl5.[3][4]
Potential synthesis
Osmium(V) chloride can be obtained in small amounts by reacting osmium hexafluoride with excess boron trichloride:[5]
- 2OsF6 + 4BCl3 → 2OsCl5 + 4BF3 + Cl2
It can also be obtained by the action of sulfur dichloride on osmium tetroxide:[2]
- 2OsO4 + 8SCl2 + 5Cl2 → 2OsCl5 + 8SOCl2
Physical properties
Osmium(V) chloride forms a black dimeric solid, isomorphic with rhenium(V) chloride. OsCl5 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]
