New Insights into the Chemistry of Oxovanadium(iv) and Zirconium (iv) Complexes with Tridentate Coordinating Ligand

چکیده
New Oxovanadium(IV) and zirconium (IV) complexes were synthesized with tridentate ligand and characterized by elemental analysis, molar conductance measurements, molecular weight determinations, IR, electronic, and H NMR studies. The Oxovanadium(IV) complex is non-electrolyte whereas zirconium(IV) complex is 1:2 electrolytes in nature and may be formulated as[(VOL)2SO4] and [ZrL2]Cl2 respectively, where L = ethyl 2-{[(2E,3Z)-4-hydroxypent-3-en-2-ylidene]amino}-4,5,6,7-tetrahydro-1benzothiophene-3-carboxylate. The analytical data showed that the Schiff base ligand acts as tridentate toward metal ions via the azomethine nitrogen, ester carbonyl and enolic oxygen atom. Spectral studies and magnetic susceptibility measurement reveals square pyramidal geometry for VO (IV) and octahedral structure for Zr (IV) complex. These metal complexes also exhibited antibacterial activity against pathogenic strains causing urinary tract infections.

The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.
