Osmium fluoride may refer to: Osmium(IV) fluoride (osmium tetrafluoride), OsF 4; Osmium(V) fluoride (osmium pentafluoride), OsF 5; Osmium(VI) fluoride (osmium ...
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 has seven naturally occurring isotopes, five of which are stable: 187 Os, 188 Os, 189 Os, 190 Os, and (most abundant) 192 Os. At least 37 artificial radioisotopes and 20 nuclear isomers exist, with mass numbers ranging from 160 to 203; the most stable of these is 194 Os with a half-life of 6 years. [39] 186
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 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.
