Six new hexa-coordinated organotellurium(IV) complexes of type RTeCl3·NMeIPT andR2TeCl2·NMeIPT (R = 4-hydroxyphenyl, 4-methoxyphenyl or 3-methy-4-hydroxyphenyl; NMeIPT(L)= Schiff base (1-methyl-3-(p-tolylimino)indolin-2-one) derived from condensation of 4-methylisatinand p-toluidine) have been synthesized and characterized by different spectral studies like elementalanalyses, molar conductance, infrared, mass spectrometry, 1H NMR, 13C NMR and UV-visiblespectroscopy. On the basis of spectroscopic data, it is evident that Schiff base behaves as NO donorbidentate ligand via azomethine nitrogen atom and oxygen atom from carbonyl group for all thetellurium(IV) complexes. The results showed that all the organotellurium(IV) complexes possessdistorted octahedral geometry. Geometry of the all organotellurium(IV) complexes was optimizedand their theoretical quantum mechanical parameters were calculated. This computational study alsosuggests octahedral geometry for complexes. The antimicrobial activity of NMeIPT and all theorganotellurium(IV) complexes were screened against bacteria i.e. Xanthomonas campestris andBacillus cereus and fungi i.e. Fusarium oxysporum, Candida albicans and Sclerotinia sclerotium.
