Examples
Embodiment 1
[0016] Example 1: Weigh 1 mmol of iridium trichloride and add it to a three-necked flask containing 50 ml of carbon tetrachloride solvent, and heat until the iridium trichloride dissolves completely. 6mmol of hexafluoroacetylacetone was carefully added dropwise, and the mixture was heated at 60°C for 45 hours. The reaction formula is as follows:
[0017]
[0018] The hot mixture was suction filtered to remove a small amount of white solid, then the solution was evaporated to dryness, the resulting solid was dissolved in 30 ml of carbon tetrachloride solution at 20°C, the solution was filtered, and the filtrate was placed in The temperature was 5°C and kept in a refrigerator for 24 hours. During this time, yellow crystals of hexafluoroacetylacetone of iridium appeared. Filter, wash and dry in vacuo. product is obtained.
Embodiment 2
[0019] Example 2: Weigh 1 mmol of iridium trichloride and add it to a three-necked flask containing 50 ml of cyclohexane solvent, and heat until the iridium trichloride is completely dissolved. 7mmol of hexafluoroacetylacetone was carefully added dropwise, then the mixture was heated at 50°C for 60 hours, the reaction formula was the same as in Example 1; the hot mixture was suction filtered to remove a small amount of white solid, and then the solution was evaporated to dryness, The obtained solid was dissolved in 30 ml of a cyclohexane solution at a temperature of 20°C, the solution was filtered, and the filtrate was kept in a refrigerator at a temperature of 5°C for 24 hours. During this time, yellow crystals of hexafluoroacetylacetone of iridium appeared. Filter, wash and dry in vacuo. product is obtained.
Embodiment 3
[0020] Example 3: Weigh 1 mmol of iridium trichloride and add it to a three-necked flask containing 50 ml of hexane solvent, and heat until the iridium trichloride is completely dissolved. 8mmol of hexafluoroacetylacetone was carefully added dropwise, and then the mixture was heated at 60°C for 48 hours, the reaction formula was the same as in Example 1; the hot mixture was suction filtered to remove a small amount of white solid, and then the solution was evaporated to dryness, The obtained solid was dissolved in 30 ml of hexane at a temperature of 20°C, the solution was filtered, and the filtrate was kept in a refrigerator at a temperature of 5°C for 24 hours. During this time, yellow crystals of hexafluoroacetylacetone of iridium appeared. Filter, wash and dry in vacuo. product is obtained.
