Abstract
The Al-27, N-15, C-13 and H-1 NMR spectra in DMSO and mass spectra of 2:1 a luminium(III) complexes (1b-4b) derived from anthranilic acid azo coupling products with 4-tert.butylphenol (1a), 2-naphthol (2a) acetoacetanilide (3a ) 3-methyl-1-phenylpyrazol-5-one (4a) were measured and analysed. It was fo und that the aluminium atom was six-coordinated, being bound to two oxygens and the nitrogen originating from anthranilic acid. (C) 2001 Published by Elsevier Science Ltd.
