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.

In this report, synthesis and characterization of gold nanoparticles (AuNPs) from gold leaf by electrolysis in two different media (gel and paper) in presence of sodium chloride (NaCl), glucose (C6H12O6) and polyvinyl pyrrolidone (PVP) at room temperature were investigated. Graphite was used as two electrodes, NaCl was used as an electrolyte, C6H12O6 was used as reducing agent and PVP was used as stabilizer to control the aggregation of the nanoparticles. UV-Visible spectroscopy (UV-Vis) and scanning electron microscopy (SEM) were used to confirm the characteristics and morphologies of the synthesized AuNPs.
