The thiourea derivatives N¹-benzoyi-N²-(5-phenyl-1,3,4-oxadiazole-2-yl)thiocarbamide (BPODTC) and N¹-benzoyl-N²(5-p-anisyl-1,3,4-oxadiazole-2-yl)thiocarbamide (BAODTC) are utilised for the preparation of Co^II, Ni^IIand Cu^ll complexes in ethanol medium. The structure of the complexes has been studied with the help of analytical and magnetic susceptibility data, uv and ir spectral measurements, conductometric and thermogravimetric analyses. The crystal field parameters of Co^II and Ni^II are also calculated. BPODTC acts as a bidentate ligand whereas BAODTC a tridentate one. [M₂(BAODTC)₂X₄ 1 and [M(BPODTC)₂X₂. where M=Co^II, Cu^II, X=CI^-, Br^- $N{O}_3^{-}$ and $CI{O}_4^{-}$; have octahedral and distorted octahedral configurations, respectively, whereas [Ni₂ ( BAODTC)₂ X₄ ) is found to be octahedral and [Ni(BPODTC)₂},X₂. square planner in ~ature. low molar conductance values in acetone except that of [Ni(BPODTC)₂]X. which is ionic, indicate that all these complexes are non-electrolytic.
