A new binuclear complexes of Ni+2, Pd+2, Zn+2, Cd+2 and Hg+2 ions with [H3L] {where H3L= 4-Methyl-2,6-bis(formylthiosemicarbazonyl) phenol}. The ligand was prepared from reaction two equivalent of thiosemicarbazide with 2,6-diformyl-p-cresol and then reacted with metal ions to form the title complexes. The ligand and complexes were characterized by {IR, UV-Vis, 1H, 13C, 1H-13C NMR and mass spectroscopy}, molar conductivity, atomic absorption and the microanalysis of elements (C.H.N). The spectral studies showed the geometry around the Ni+2 and Pd+2 ions are square planar and the Zn+2, Cd+2 and Hg+2 ions are distorted tetrahedral.
