Osmium(II) iodide is a black solid [35] produced by the reaction of osmium tetroxide and hydroiodic acid at 250 °C in nitrogen: [34] OsO 4 + HI → OsI 2 + H 2 O. This compound decomposes in contact with water. [35] Osmium(III) iodide is a black solid that is produced by heating hexaiodoosmic acid (H 2 OsI 6). [34] This compound is insoluble ...

Osmium octafluoride is an inorganic chemical compound of osmium metal and fluorine with the chemical formula Os F 8. [ 3 ] [ 4 ] Some sources consider it to be a still hypothetical compound . [ 5 ] An early report of the synthesis of OsF 8 was much later shown to be a mistaken identification of OsF 6 . [ 6 ]
4] are used in the synthesis of osmium cluster compounds. [29] [30] Osmium tetroxide (OsO 4) The most common compound exhibiting the +8 oxidation state is osmium tetroxide (OsO 4). This toxic compound is formed when powdered osmium is exposed to air. It is a very volatile, water-soluble, pale yellow, crystalline solid with a strong smell.

It was first reported in 1909 as the product of chlorination of osmium metal. [1] This route affords the high temperature polymorph: [2] Os + 2 Cl 2 → OsCl 4. This reddish-black polymorph is orthorhombic and adopts a structure in which osmium centres are octahedrally coordinated, sharing opposite edges of the OsCl 6 octahedra to form a chain. [3]
