摘要

The mixed-ligand copper(II) iminodiacetates [Cu(ida)(2-mim)(H O) ]·H O ( ), [Cu(ida)(2-mim) ]·2H O ( ), [Cu(ida)(2-mim)(H O)] ·4.5nH O ( ), and [Cu (ida) (2-mim) ] ·nH O ( ) (H ida = iminodiacetic acid, 2-mim = 2-methylimidazole) were obtained from neutral or alkaline solutions at different temperatures. The novel complex contains very small holes with diameters of 2.9 Å, which can adsorb O selectively and reversibly between 1.89 to 29.90 bars, compared with the different gases of N , H , CO , and CH . This complex is stable up to 150 °C based on thermal analyses and XRD patterns. The four complexes show catalytic activities that facilitate the conversion of cyclohexane to cyclohexanol and cyclohexanone with hydrogen peroxide in a solution. The total conversion is 31% for .
