Шаблон:Chembox Iridium(II) chloride is an inorganic chemical compound of iridium metal and chlorine with the chemical formula Шаблон:Chem2.[1][2] This is a metal salt of iridium and hydrochloric acid.
Synthesis
- The substance is obtained by the interaction of powdered metallic iridium with chlorine gas when heated:[3][4]
- Iridium(II) chloride can also be made in a reaction between iridium(III) chloride and metallic iridium:
Physical properties
Iridium dichloride forms shiny dark-green crystals that are practically insoluble in water.[5] Poorly soluble in acids and alkali. When heated to 773 °C, Шаблон:Chem2 decomposes without melting.
The standard Gibbs energy of the formation of ΔG (298 K, kJ/mol) is -139.7.
Chemical properties
When heated to 773 °C decomposes according to the equation:[6]
At temperatures above 798 °C, complete decomposition of the substance occurs:
