This article reports the synthesis, characterization and antimicrobial screening of a tridentate2-[(2-hydroxyphenyl)imino methyl]-1-naphthol ligand (H2AP) and its organotellurium(IV) complexes.Structural characterization of the synthesized ligand and complexes was confirmed by using FT-IR,1H NMR, 13C NMR, UV-vis, mass spectrometry, molar conductance and elemental analysis. Geometryof all the synthesized compounds has been optimized and their DFT based chemical reactivitydescriptors were calculated. DFT and spectral data studies revealed distorted square pyramidal geometryfor the tellurium(IV) complexes. In vitro antimicrobial activities of the synthesized ligand and itstellurium(IV)complexes were evaluated against two Gram-positive, two Gram-negative bacterial strainsand three fungal strains. The tellurium(IV) complexes exhibited promising activity as compared to theSchiff base ligand.
