Abstract

This paper deals with the preparation and investigation studies of a number of new complexes of Cu(II), Zn(II), Hg(II), Ag(I), Pt(IV), and Pb(II). The complexes were formed by the reaction of the mentioned metal ions with the ligand which is derived from oxadiazole (OXB), 2-(2-butyl) thio-5-phenyl–1,3,4–oxadiazole in the mole ratio (1:1), (1:2) and (1:3) (metal to ligand). The result complexes having general formulae: [M(OXB)Cl2], [M(OXB)X2]H2O [M = Cu(II), Zn(II), M = Hg(II), Pb(II)] [M(OXB)2X2] X = Cl– M = Cu(II), Zn(II), Hg(II), Pb(II) X = Cl–, NO3-, CH3COO- [Pt(OXB)3]Cl4, [Ag(OXB)]NO3^2– (2-thio-5-phenyl–4,3,1–oxadiazole) OXB = These complexes have been characterized by a variety of chemical, physical, and spectroscopic techniques, such as elemental analysis, molar conductance, Infrared absorption spectra, electronic spectra, and magnetic susceptibility measurements. These studies indicate that the tetracoordinate complexes have either square planar or tetrahedral structures, and the hexacoordinate complexes, while bidentate, complexes for Ag(I) have been found to have non-linear (deviated) structure. Furthermore, the prepared complexes' ability was tested as their bactericidal materials.
