Abstract

TWO models of azo disprse dye complexes were prepared by the reaction of 3-hydroxy- 4- ((2-hydroxyphenyl) diazenyl)-2-naphthoic acid (H 2L) with a divalent Cu(II) and Co(II) ions. The structures were confirmed by elemental analysis, spectral studies (1H NMR, IR, UV–visible, ESR), and magnetic measurements. IR spectra of the isolated complexes suggest that the H2L acts as a tetradentate ligand. The electronic spectra of the complexes and their magnetic moments suggest octahedral geometry. These dyes were applied to nylon 6 and wool fabrics. The results assessed for dyeing indicate an improving in washing and slightly enhanced in rubbing fastness rather than Fe (III) and Cr (III) complexes on wool fabrics , But approximately the same on nylon 6 fabrics.
