Abstract
Complexes of 2-(3-propionic acid) thio-5-phenyl-1,3,4-oxadiazole with Mn(II), Fe(II), Co(II), Ni(II), Cd(II), Pb(II) and Ag(I) have been synthesized and characterized on the basis of physicochemical investigations including infrared and electronic spectroscopy, magnetic moment measurements, molar conductance and elemental analysis.
The have been assigned the formula: [M(OXP)(H2O)3]Cl; where M=Mn(II), or Fe(II), [M(OXP)2], Where M=Mn(II), Fe(II), Co(II) and Ni(II), [M(OXP)(H2O)]Cl; where M= CO(II), Ni(II), Cd(II) and Pb(II) and [Ag(OXP)] (NO3).
Infrared spectral data suggest that the ligand OXP: behaves as a, monobasic tridentate ligand with N,S,O donor sequence towards the metal ions expect the silver (I); it acts as neutral bidentate ligand coordinating via N,S atoms. On the basis of the above physicochemical data,octahedral, tetrahedral and non linear geometries were assigned for the complexes.The ligand and its complexes were screened for their antifungal activities against two species of fungi, Trichoderma and Aureobasidium; and it was found that the complexes possess certain degree of activity
