Red Onion skin extract (ROSE)azo compound of 2-aminophenol and Cu (II) metal complex of the azo compound (Cu-APmROSE) were formed and characterized using FT-IR spectroscopy, UVVisible absorption spectroscopy and Scanning electron microscopy. The IR Spectra showed the values of N=Nstretching frequency of 1512.24cm at 1500 cm in APmROSE. This stretching frequency is absent in the Cu-APmROSE. This is an indication of the involvement of the N=Nbond in coordination to the metal. APmROSE shows an absorption maximum at 512 nm. This band was shifted to 334 nm in Cu-APmROSE. This suggests an interaction between the Cu and the azo compound.
