Chromium (III) Schiff base complexes have been synthesized using Schiff base formed by the condensing by the respective aldehyde with diamene in ethanol (rectified). All the complexes were characterized on the basis of their micro analytical data, elemental analysis, melting points, IR, UV- vis spectra and magnetic moment properties. The magnetic moment suggest that all the complexes are in the range 3.6-4.1 indicating the three unpaired electron. The infrared spectrum of the complexes under investigation confirmed the site of chelation, hence the complexes showed stretching due to n(C=N) and n(C-O) which suggest the involvement of phenolic group in the coordination. The UV-Vis spectral data shows the π →π^* transition which suggest to involves molecular orbital π  localized at the azomethane linkage.
