A new Schiff base ligand, 4,5,9,13,14-pentaaza benzo[b] triphenylen was synthesized by condensation reaction of 2,3-diaminopyridine and 1,10- phenanthroline-5,6-dione. Cu(II) and Ni(II) nanocomplexes were synthesized by the reaction of ligand and melt salt by solvothermal and sonochemistry method. The ligand and its metal complexes have been characterized by CHN, FT-IR, 1H and 13CNMR, UV–Vis, thermal gravimetric analyses (TGA,DSC) and conductivity measurements. CuO and NiO nano-structures were synthesized from [Cu(pdp)2 CIO4 2 and [Ni(pdp)2](ClO4)2 by calcination in air atmosphere. The structures of the nano-structures were characterized by XRD and SEM tecchniques. The thermal stability of nano-sized and bulk samples of complexes were studied and compared with each other.
