The 27 Al, 15 N, 13 C and 1 H NMR spectra in DMSO and 27 Al and 15 N 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 that the aluminium atom is six‐coordinated, being bound to two oxygens and the nitrogen originating from 2‐hydroxy‐5‐chloroaniline of each ligand, in an analogous fashion to 2:1 cobalt(III) complexes described earlier. © 1998 John Wiley & Sons, Ltd.
