Schiff bases are one of the important classes of organic compounds containing imine or azomethine functional groups with potential biological applications in medicinal chemistry. These bases played a significant role in developing inorganic, bioinorganic, and optical materials and coordination complexes. Nowadays, these compounds have attracted the scientific community's attention due to their ability to act as ligands in the formation of stable metal complexes with significant biological activity. In this connection, we have designed and synthesized some novel thiophene‐based organoltellurium (IV) complexes using a novel N‐((5‐methylthiophen‐2‐yl) methylene)‐2‐nitroaniline (5MTCONA) schiff base. The synthesized schiff base and organotellurium complexes were characterized with FT‐IR, Mass spectrometry, 1H NMR, 13C NMR, Powder XRD, and TGA. The in‐vitro pharmacological evaluation of these compounds has been carried out as antimicrobial and antioxidant agents. The theoretical studies (Semi empirical PM3 method, Molecular Docking, and ADMET) of all the compounds have also been carried out with Spartan‐14, Hex‐8.0., Swiss ADME software to support the experimental investigations and observed that both the results are in correlation with each other.
