Acid-base properties of 2',2'-diethylheptanohydrazide (DEHH) and its complex formation with copper(II) ions in water-isopropanol solutions were studied. Cationic complexes with [Cu2+] : [DEHH] ratios of 1 : 1 and 1 : 2 were found to be formed in weak acid media, and an uncharged complex with a [Cu2+] : [DEHH] ratio of 1 : 2 was found to be formed in a basic medium. log K (st) values were determined. The data obtained were compared with the stability constants of copper(II) 2',2'-diethylbenzohydrazide complexes.
