  • Abstract

    A novel monobasic tridentate Schiff base salicylidene-trimethoprim, Sal-TMP, synthesized from trimethoprim and salicylaldehyde, form stable complexes with aryltellurium(IV) trichlorides and diaryltellurium(IV) dichlorides of the type Sal-TMP.ArTeCl2 and Sal-TMP.Ar2TeCl (where Ar = p-methoxyphenyl, p-ethoxyphenyl, p-hydroxyphenyl and 3-methyl-4-hydroxyphenyl). These have been characterized by elemental analyses, molar conductance, IR and 1H NMR spectroscopy. The spectral studies predict the bonding of ligand through phenolic oxygen of Schiff base after deprotonation, nitrogen of the azomethine group and pyrimidine nitrogen to give hexa-coordinated tellurium(IV) complexes. The complexes have also been screened for their antimicrobial activities against various bacteria and fungi organisms
