الملخص EN

A new ligand [a4-methylbenzaldehyde[5-(3-furyl)-1,3,4-oxadiazol-2-yl]hydrazine] (L) and its Cr(III),Fe(III) Co(II), Ni(II)and Cu(II) complexes were synthesized.

The authenticity of the ligand and its transition metal complexes were established by elemental analyses and conductance measurements, as well as spectroscopic (IR, 1HNMR, mass).

.

It may be concluded that the ligand coordinate through Nitrogen atoms.

for all the complexes.

This view is further supported by the appearance of a band corresponding to the metal–nitrogen stretching vibration atcm–1 in the complexes.

The molar conductance studies suggest an tetrahedral and octahedral geometry of the complexes .the Ni and Cu atoms leading to the formation tetrahedral geometry .Octahedral geometry was proposed for the(Cr(III),Fe(III)andCo(III)prepared complexes
