To analyze the geometrical and topological parameters of the3-MDPYP molecule, the quantum chemical calculations using Density Function Theory (DFT) is performed. This method along with the 6-311G** basis set, confirms the exact geometry of the selected molecule. The vital role of Piperidin-4-ones and its derivatives are found to have great potential in terms of becoming potent compounds in drug design. In this regard, characterizing such compounds to study theoretically and their structure becomes important and economical in performing the suitability test. This paper is a record of such research attempt on studying geometrical properties like the bond angle, bond lengths, torsion angles and bond topological properties of the 3-MDPYP molecule.
