PREPARATION AND CHARACTERISATION OF SOME TRANSITION METAL COMPLEXES OF NEW 4-[(5-ETHYL-1,3,4-OXADIAZOL-2-YL)SULFANYL]ANILINE

1,3,4-oxadiazoles are important because of its versatile biological actions such as antimicrobial , anti-malarial , anticonvulsant , hypoglycemic, also analgesic, anti-inflammatory, anticancer, anti-HIV agent .In the present study The solid complexes of Fe(II), Cr(III), Co(II), Ni(II), and Cu(II)) with Synthesis of 4-[(5-ethyl-1,3,4-oxadiazol-2-yl)sulfanyl]aniline have been synthesized and characterized by using the spec-troscopic IR,1HNMR, Mass as well as by elemental analyses C,H,N and Molar conductancethey were studied . It may be concluded that the ligands coordinate through Nitrogen and Sulfur as atoms shown in Scheme (2). For all the complexes. The ligand acts as a didentate ligand coordinating through the oxadiazole nitrogen and the Sulfur atom of 2-sulfanyl. This view is further supported by the appearance of a band corresponding to the metal?nitrogen and the metal?Sulfur stretching vibration at 503?553 cm?1 and 474-484 cm?1 in the complexes. The physicochemical data suggest the octahedral geometry for all complexes except for Ni and Ca complexes which where tetrahedral respectively.
