Abstract: The solid complexes of Fe (III), Cr (III), Co (II), Ni (II), andCu (II)) with Synthesis of N- [5- (4-methylphenyl) -1, 3, 4-thiadiazol-2-yl]acetamide have been synthesized and characterized by using the spectroscopic IR, 1HNMR, Mass as well as by elemental analyses C, H, N and Molar conductance the were studied. It may be concluded that the ligand coordinate through Nitrogen atoms and oxygen atoms shown in Scheme (2). for all the complexes. It may be concluded that the ligand coordinate through C=N thiadiazol and C=O as the ligand. for all the complexes. This view is further supported by the appearance of a band corresponding to the metalnitrogen stretching vibration at (597 442-) cm1 and the metaloxygen stretching vibration at (341-372) cm1 in the complexe. The physicochemical data suggest the octahedral geometry for all complexes except for Ni and Cu complexes which were tetrahedral respectively
