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 fluoride may refer to: Osmium(IV) fluoride (osmium tetrafluoride), OsF 4; Osmium(V) fluoride (osmium pentafluoride), OsF 5; Osmium(VI) fluoride (osmium ...

Osmium (from Ancient Greek ὀσμή (osmḗ) 'smell') is a chemical element; it has symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Osmium is the densest naturally occurring element.
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 ]

The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
