Kavitha and Lakshmi have also reported the synthesis and characterization of Co(II) Schiff base metal complex obtained from the reaction of the ligand 3- oxazin-2-one (obtained from the reaction of 3-hydrazino-1,4-benzoxazin-2-one and 2,4-dihydroxyacetophenone), and CoCl2. The result of the IR Spectra, showed broad peak at 3430 cm _1 due to the stretching vibration of (OH) (phenolic) A sharp peak at 3268 cm _1 was assigned to the stretching vibration of N-H moiety. The strong bands at 1603 and 1567 cm _1 were attributed to vibration bands of C=O and azomethine groups. The decrease of the band assigned to the zomethine group compared th the value obtained in the spectrum of the ligand were due to participation of the nitrogen atom of the imine group in coordination. The Uv-Vis spectrum gave bands at 37,735 cm _1 and 33,670 cm _1 due to π-π* and n-π* transition respectively of the ligand. These bands were seen at 31,948 and 31,645 cm _1 in the spectrum of the complex. The magnetic moments of Co(II) was found to be 5.27B.M which indicates that the complex conformed to an octahedral geometry.
