An azo dye derived from 3-aminophenol and its cobalt complex have been synthesized and characterized using Fourier transformed and ultraviolet visible spectrophotometer. The ligand (dye) exhibited an absorption maximum at 470 nm but the absorbance maxima for the synthesized Schiff base complex deviated from 470 to 473 nm which indicated the existent of interaction between the cobalt and the ligand to form metal-dye complex. Moreover, the infrared absorbance band for -N=N- stretching vibration at 1513.3 cm-1 for azo dye nut in the complex the frequency shifted to 1457.4 cm-1. The calculated percentage yield of the azo dye was found to be 84% while that of its cobalt complex was 59%.
