Synthesis, Investigation and X-Ray Powder Diffraction (XRD) of Some Oxadiazole Complexes

Abstract

New ligand; 2-(1,1-dimethoxymethane) thio-5-(phenyl)-1,3,4-oxadiazole (L)(3) and its complexes with Mn(II), Fe(III),Co(II), Ni(II), Cd(II) and Zr(IV), have been synthesized and characterized onthe basis of physicochemical investigations including infrared and electronicspectroscopy,magnetic moment measurements, molar conductance and elementalanalysis. The structures of the compounds and some complexes have beeninvestigated by X-ray powder diffraction and H1NMR spectra. was recorded onbroker shield 300 MHz using deutrated DMSO-d6 as a solvent. for ligand. Theyhave been found to have the formula; [M L (H2O)3Cl]Cln; M= Mn(II ) n = 1, (4)and M=  Fe(III), n = 2  (5), [ML (H2O) Cl)] Cl , M=. Co(II) (7), Cd(II) (8)and [NiLCl2](6) ,[ZrOL(H2O)Cl2]Cl2 (9), in molar ratio 1:1. Infrared spectral data suggest that the ligandL: behaves as a, bidentate ligand with N,S, donor sequence towards the metalions. According to the above physicochemical data, octahedral and tetrahedralgeometries were assigned for the complexes.
