Add to ORKGCommunication in Physical Sciences 2020, 6(1): 722-725 Gideon Wyasu*, B. Myek and Sunday Solomon Received 19 May 2020/Accepted 20 September 2020 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 pe...
