New Co(II), Ni(II) and Cu(II) complexes with  2-meracapto-5-(2,4-dinitrophenyl)-1,3,4-oxadiazole (IpotH) or 2-meracapto-5-((4-(dimethylamino)benzylidene)amino)-1,3,4-thiadiazole (daptH)  ligands, were prepared by treatment two moles of thione ligands  with one mole of metal salts in EtOH/Acetone and H₂O as a solvents, to afforded octahedral complexes of the  types  [MX₂(k²-IpotH)₂] (Where M = Co, Cu, X= Cl and M= Ni , X= NO₃ ) or [MX₂(k²-daptH)₂] (Where M = Co, Cu, X= Cl and M= Ni , X= NO₃ ). The thione ligands bonded through the nitrogen atom of heterocylic and sulfur atom of thiol group. The prepared ligands and its complexes were characterization by elemental analysis (CHNM), IR spectroscopy , molar conductivity, magnetic susceptibility, UV-Visible spectroscopy and ¹H NMR data.
