Co(II), Ni(II), and Cu(II) complexes with tetradentate schiff base-<TEX>$NOTDH_2$</TEX>, were synthesized. The structures of these complexes were characterized by elemental analysis, IR, UV-visible, NMR spectra, and thermogravimetric analysis. The mole ratio of schiff base(<TEX>$NOTDH_2$</TEX>) to the metal(II) at complexes was found to be 1:1. Cu(II) complexes were four-coordinated configuration, while Co(II) and Ni(II) complexes were hexacoordinated configuration containing two water molecules and all complexes were non-ionic compounds.
