Summary, etc. A series of nickel (II) and copper (II) complexes viz. [Ni(L<sup>1</sup>)<sub>2</sub>](<strong>1</strong>), [Cu(L<sup>1</sup>)<sub>2</sub>](<strong>2</strong>), [Ni(L<sup>2</sup>)<sub>2</sub>](<strong>3</strong>) and [Cu(L<sup>2</sup>)<sub>2</sub>](<strong>4</strong>) (Where <strong><em> </em>L<sup>1</sup>H</strong>= (<em>E</em>)-N-phenyl-2-(thiophen-2-ylmethylene)hydrazine-1-carboxamide, <strong>L<sup>2</sup>H= </strong>(<em>E</em>)-2-((3-methylthiophen-2-yl) methylene)-N-phenylhydrazine-1-carbothioamide), have been synthesized and designed as  potential inhibitors against SARS-CoV-2 and HIV-1 virus. The quantum computational calculations are used for structure-property relationship. A detailed structural and non-covalent supramolecular interaction in the ligand (<strong>L<sup>1</sup>H</strong>) is investigated by single crystal structure analysis and computational approaches. Hirshfeld surface analysis was done in the crystal structure of the ligand (<strong>L<sup>1</sup>H</strong>), while 3D topology of the crystal packing is visualized through an energy framework. To find potential inhibitors of the SARS-CoV-2 and HIV-1 virus, molecular docking of the ligands and their corresponding metal complexes with SARS-CoV-2 and HIV-1 virus was performed.  The X-ray crystallographic structure of the main protease of the SARS-CoV-2 (PDB ID: 7VNB) and HIV-1 virus (PDB ID: 1REV) was retrieved from the protein data bank and used as receptor proteins. The molecular docking results showed that Schiff bases and their complexes with SARS-CoV-2 and HIV-1 virus exhibited good binding affinity at binding site of receptor protein. It was observed that the binding affinities of the Schiff bases and metal complexes towards SARS-CoV-2 were comparatively higher than the HIV virus.  This study may offer the new antivirus drug candidates against SARS-CoV-2 and HIV-1 virus.
