Osmium(IV) chloride or osmium tetrachloride is the chemical compound composed of osmium and chlorine with the formula OsCl4. It forms reddish-black orthorhombic crystals[1], in which osmium atoms are octahedrally coordinated with sharing of opposite edges of the OsCl6 octahedra to form a chain.[2] It is an oxidizing agent.
Reactions
Osmium(IV) chloride is formed by dissolving Osmium(VIII) oxide in concentrated hydrochloric acid [3]
- OsO4 + 8 HCl → OsCl4 + 4 H2O + 2 Cl2
or by heating elemental osmium with chlorine at high pressures[4]:
- Os + 2Cl2 → OsCl4
Osmium(VIII) oxide can be formed by the oxidation of osmium(IV) chloride with sodium hypochlorite[5].
- OsCl4 + 4 NaClO → OsO4 + 4 NaCl + 2 Cl2
