6, and its ammonium salt are common iridium compounds from both industrial and preparative perspectives. [37] They are intermediates in the purification of iridium and used as precursors for most other iridium compounds, as well as in the preparation of anode coatings. The IrCl 2−
Iridium compounds are compounds containing the element iridium (Ir). Iridium forms compounds in oxidation states between −3 and +9, but the most common oxidation states are +1, +2, +3, and +4. [2] Well-characterized compounds containing iridium in the +6 oxidation state include IrF 6 and the oxides Sr 2 MgIrO 6 and Sr 2 CaIrO 6.
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 ...

Naturally occurring platinum and platinum-rich alloys were known by pre-Columbian Americans for many years. [5] However, even though the metal was used by pre-Columbian peoples, the first European reference to platinum appears in 1557 in the writings of the Italian humanist Julius Caesar Scaliger (1484–1558) as a description of a mysterious metal found in Central American mines between ...
Outlook: Iridium anticipates a 5% growth in service revenue for FY24, compared to the previous estimate of 4% to 6%, and expects OEBITDA to be between $465 million and $470 million, revised from ...
Experiencing male pattern baldness might be common, but that doesn’t make the process any more enjoyable. In fact, many men struggle as they watch their hairlines recede. If you’ve been told ...
This dark red solid is the ammonium salt of the iridium(IV) complex [IrCl 6] 2−. It is a commercially important iridium compound, [1] one of the most common complexes of iridium(IV). A related but ill-defined compound is iridium tetrachloride, which has been used interchangeably. [2]
