Dear Tarek A very elegant way to get molecular coordinates is via SMILES (symbolic molecular specs) and OpenBabel. SMILES:  https://en.wikipedia.org/wiki/Simplified_molecular-input_line-entry_system OpenBabel: converts SMILES string to 3D coordinates http://openbabel.org/ (on Debian-based linux

Dear Tarek Hammad You can easily build a molecular structure with the Avogadro GUI https://avogadro.cc/ and preoptimize it with its built-in force field. If your molecule has a lot of conformers/rotamers you should find and sort them to identify the global minimum. An excellent and easy to
