An efficient synthesis of ligand N-phenyl-N′-(4′-methylthiazol-2′-yl)-thiourea via the reaction of 2-amino-4-methylthiazol and Phenylisothiocyanate under mild conditions has been developed. This reaction proceeded well at room temperature, to products in excellent yields for a wide range of substrate. The corresponding complexes of these ligand were synthesized by the reaction of the ligand with Pd(II), Pt(II) at molar ratio of 1:2. The structures of complexes were identified by physicchemical and spectroscopic techniques (IR, Mass spectrometry). IR spectrum of the ligand displays two bands at 3340 cm-1 and 3165cm-1, attributable to υ(N1–H), υ(N2-H), respectively. The IR spectra of the complexes showed stretching frequency for the N2H group and the disappearance of the band of N1H. The disappearance or absence of the strong band at 650cm-1 in the free ligands is a strong evidence for the coordination of the nitrogen atoms of the thiazole ring in the metal complexes. The mass spectrum of the PdL2 complex revealed the highest peak at m/z = 602 corresponds to the molecular weight of the parent cationic species [M]+. This assigns mentis based on the atomic weight of Pd-106 isotope. The mass spectrum of the [PtL2ClH2O] complex revealed the highest two peak with low intensity at m/z = 692 and 693, based on atomic weight of Pt-195 and Pt-196, respectively, among the isotope cluster peaks assigned to a molecular ion of the complex. The mass spectrum of the [PtL1 2].4H2O complex revealed the highest peak at m/z = 691 corresponds to the molecular weight of the parent cationic species [M]+. This assign mentis based on the atomic weight of Pt-165 isotope among the isotope cluster peaks assigned to a molecular ion of the complex. This corresponds to the molecular weight of the nonaqueous cationic complex PtL2
