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 dichloride on osmium 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]
