## Abstract The ^15^N, ^13^C and ^1^H NMR spectra of 2:1 cobalt(III) complexes of azo dyes and their ^15^N isotopomers, derived from substituted 2‐hydroxyaniline azo coupling products with acetoacetanilide, were measured. It was found that, in contrast to precursors existing fully in their hydrazon
