Abstract
Schiff bases are one of the important classes of organic compounds containing imine or azomethine functional groups with potential biological applications in medicinal chemistry. 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 six novel thiophene-based organoltellurium (IV) complexes using a novel N-((5-methylthiophen-2-yl) methylene)-2-nitroaniline (5MTCONA) schiff base. These complexes underwent analytical investigation (TGA, Powder XRD, SEM, EDAX) as well as spectral analysis (FT-IR, NMR, Mass spectrometry, UV-Vis). The in-vitro pharmacological evaluation of these compounds has been carried out as antimicrobial and antioxidant agents. To further corroborate our findings, we have implemented computational analyses (Semi empirical PM3 method, Molecular Docking, and ADMET) of all the compounds with Spartan-14, Hex-8.0., Swiss ADME software. Precisely, our study integrates experimental and theoretical aspects, offering innovative insights in the field of pharmaceutical sciences.

Abstract
Novel thiophene-derived Schiff base ligand DE, where DE is (E)-N1,N1-diethyl-N2-(thiophen-2-ylmethylene)ethane-1,2-diamine, and the corresponding M(II) complexes, [M(DE)X2] (M = Cu or Zn, X = Cl; M = Cd, X = Br), were prepared and structurally characterized. X-ray diffraction studies revealed that the geometry around the center of the M(II) complexes, [Zn(DE)Cl2] and [Cd(DE)Br2], could be best described as a distorted tetrahedral. In vitro antimicrobial screening of DE and its corresponding M(II) complexes, [M(DE)X2], was performed. The complexes were more potent and showed higher activities against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa, fungi Candida albicans, and protozoa Leishmania major compared to the ligand. Among the studied complexes, [Cd(DE)Br2] exhibited the most promising antimicrobial activity against all the tested microbes compared to its analogs. These results were further supported by molecular docking studies. We believe that these complexes may significantly contribute to the efficient designing of metal-derived agents to treat microbial infections.
