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.
