Osmium(V) chloride is an inorganic chemical compound of osmium metal and chlorine with the chemical formula OsCl5.[3][4]
Osmium(V) chloride can be obtained in small amounts by reacting osmium hexafluoride with excess boron trichloride:[5]
It can also be obtained by the action of sulfur dichlorideonosmium tetroxide:[2]
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]
