The vibration band for phenolic C-O of ligand was observed at 1171 cm _1 . The strong band at 1603 cm -1 was attributed to the lactone carbonyl group. A broad band with a shoulder at 1567 cm _1 was attributed to azomethine group. The m(N-N) bending vibration is noticed at 1058 cm -1 . A small band noticed at 3038 cm -1 was ascribed to CH group of the aromatic ring while the asymmetric CH stretching of the aliphatic group is observed at 2924.
