ABSTRACT The solid complexes of Fe(II), Cr(III), Co(II), Ni(II), andCu(II)) with Synthesis of [Butanal(5-ethyl-1,3,4-oxadiazol- 2-yl)hydrazone]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 shown in Scheme (2). For all the complexes. The ligand acts as a didentate ligand coordinating through the oxadiazole nitrogen and the nitrogen of C=N group .This view is further supported by the appearance of a band corresponding to the metal?nitrogen stretching vibration at 513?540 cm?1 in the complexes. The physicochemical data suggest the octahedral geometry for all complexes except for Ni and Cu complexes which were tetrahedral respectively.
