    Another oxide, iridium tetroxide, is also known, with iridium in the +8 oxiation state. [7] This compound was formed by photochemical rearrangement of [(η 1-O 2)IrO 2] in solid argon at a temperature of 6 K (−267.15 °C; −448.87 °F). At higher temperatures, the oxide is unstable. [8] The detection of the iridium tetroxide cation IrO +

    en.wikipedia.org/wiki/Organoiridium_chemistry

    Organoiridium compounds share many characteristics with those of rhodium, but less so with cobalt. Iridium can exist in oxidation states of -III to +V, but iridium(I) and iridium(III) are the more common. iridium(I) compounds (d 8 configuration) usually occur with square planar or trigonal bipyramidal geometries, whereas iridium(III) compounds (d 6 configuration) typically have an octahedral ...

  7. Iridium(III) bromide - Wikipedia

    en.wikipedia.org/wiki/Iridium(III)_bromide

    Iridium(III) bromide is a dark reddish-brown solid that is insoluble soluble in water, acids, and alkalis and decomposes to iridium(II) bromide on heating. [1] It crystallizes in a highly disordered layered structure of aluminum(III) chloride or chromium(III) chloride type, where the monoclinic unit cell contains four formula units.
