Carbonyliridium halides are organometallic iridium compounds with the general formula Ir (CO) 3 Hal and Ir (CO) 2 Hal 2 , where Hal = singly charged chlorine , bromine and iodine ions.
Properties
Under normal conditions , Ir (CO) 3 Hal compounds form brown solids, unstable in aqueous solutions, but relatively stable in air. When heated to 115 ° C, the substances sublimate without melting.
Compounds of the type Ir (CO) 2 Hal 2 are light yellow crystals, sublime at 150 ° C. Very unstable in air, decomposing with the release of carbon monoxide:
Getting
- The reaction of iridium salts IrHal 3 with carbon monoxide (II) at 150 ° C.
