  • Abstract

    Monobasic (ON) bidentate Schiff base ligand has been prepared by condensing o-hydroxybenzaldehyde with 3-aminopyridine. The new organyltellurium(IV) complexes, having formula [TeCl3(3-APY-{Sal})], [RTeCl2(3-APY-{Sal})] and [R2TeCl(3-APY-{Sal})] have been synthesized by reacting equimolar ratio of Schiff base (3-APY-{SalH}) with TeCl4, RTeCl3 and R2TeCl2: where R=4-methoxyphenyl, 4-hydroxyphenyl, 3-methyl-4-hydroxyphenyl. The characterization of Schiff base and its complexes were carried out by elemental analyses, conductivity measurements, FTIR and 1H NMR spectral studies. Also, the biological activities (antifungal and antibacterial) of the Schiff base ligand and some of its tellurium(IV) complexes have been studied.
