Usage

General Description

Iridium hexafluoride (IrF6) is a highly reactive compound of iridium, a rare and precious metal, and fluorine, the most electronegative element. It is a volatile, dark-green crystalline solid under standard conditions and an extremely powerful fluorinating agent due to the presence of six fluorine atoms. It can be produced by the reaction of iridium metal with pure fluorine gas. Special precautions must be taken in handling and storing iridium hexafluoride because of its extreme reactivity and its potential to cause severe burns upon contact with skin and eyes.

Plasmachemical synthesis of the binary hexafluorides of Mo, Os, Ir, Te, and U

Starting from the respective metal, we have synthesized the binary hexafluorides MF6 of M = Mo, Os, Ir, Te, and U by the use of a remote fluorine plasma source using a mixture of Ar and NF3 as the feed gas. The formation of the binary hexafluorides was confirmed by several different spectroscopic methods including IR, Raman, UV/VIS, and NMR spectroscopy.

Spectroscopic Studies on the Hexafluorides of Rhenium, Osmium, Iridium, and Platinum isolated in Low-temperature Matrices

The compounds ReF6, OsF6, IrF6, and PtF6 have been isolated as monomeric species in inert-gas matrices at low temperatures, and characterised by i.r. spectroscopy.Subsequent u.v.-visible studies reveal a complex pattern of electronic absorptions, and a detailed assignment of these in terms of charge transfer, d-d, and intra-configurational transitions is presented.
