The reactions of A13+ ion with a series of aminopolycarboxylic acids containing coordinating sites (denticity, n) ranging from 3 to 8 were studied by potentiometric and "A1 NMR methods. Hydrolysis constants of the complexes were determined by potentiometry. The 27Al {'H} NMR data indicate a nearly l

## Abstract The reactions of Al^3+^ ion with glycine, picolinic acid, 1,2‐propylenediaminetetraacetic acid and triethylenetetra‐minehexaacetic acid (H~p~L) were studied by potentiometric and ^27^Al NMR methods, and the complex species in solution at different pH values were identified. Acidic hydro
The 27Al, 15N, 13C and 1H NMR spectra in DMSO and 27Al and 15N magic angle spinning NMR spectra of 2 : 1 aluminium(III) complexes derived from 5-chloro-2-hydroxyaniline azo coupling products with acetoacetanilide, 3-methyl-1-phenylpyrazol-5-one and 2-naphthol were measured and analysed. It was found
