Eight new Co(II) and Ni(II) complexes with variously substituted 1,3,4-oxadiazoles (L1-L8) have been prepared and characterized by magnetic susceptibility, molar conductance, molecular weight determination and spectral studies. All the cobalt complexes exhibit the composition Co(L)2Cl2.2HO2 and the formula Ni(L)2(SO4). 2H2O has been assigned to Ni(II) complexes. Although 1,3,4-oxadiazoles have three coordinating sites, namely two ring nitrogen and one oxygen, the spectral studies indicate that only the two ring nitrogen involved in the coordination. Electronic spectral data reveal that theses complexes have octahedral geometry.
