Disodium hexachloroiridate is an inorganic chemical compound of sodium from the group of hexachloroiridates .

Extraction and presentation

Disodium hexachloroiridate can be obtained by reacting iridium with sodium chloride in a stream of chlorine at 625 ° C. It is allowed to cool slowly in a stream of chlorine, so that any that has formed continues to grow ${\ displaystyle {\ ce {Na3 [IrCl6]}}}$

{\ displaystyle {\ ce {2 Na3 [IrCl6] + Cl2 -> 2 Na2 [IrCl6] + 2 NaCl}}}

is oxidized again.

It is also formed from iridium (IV) oxide in sodium chloride melts in the presence of chlorine.

properties

Disodium hexachloroiridate is a red-black solid that is soluble in water as a hydrate.

use

Disodium hexachloroiridate hexahydrate is used for pharmaceutical and organic intermediates and for the manufacture of other iridium (IV) complexes.
