A novel Co(III) complex derived from hexaadentate Schiff base ligand, H3L was described. The ligand is prepared from the reaction of tris-2-aminoethyl amine and o-vanillin in 1:3 molar ratio. The structure of the ligand and its Co(III) complex was described by micro-analyses, FT-IR, NMR, ESI-MS and UV/visible and thermal stability. DFT study was carried out to get insights into the ligand and its Co(III) complex to compare the values of bond lengths and angles with each other. The electronic spectra, Mulliken atomic charge distribution, HOMO-LUMO energy and the thermodynamic parameters have been calculated.
