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 ...

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.
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 ]

Osmium heptafluoride is a possible inorganic chemical compound of osmium metal and fluorine with the chemical formula OsF 7 . [ 2 ] [ 3 ] It was first reported in 1966 by the reaction of fluorine and osmium at 600 °C and 400 atm, [ 4 ] but no purported synthesis could be reproduced in 2006, giving only osmium hexafluoride instead.
