In this context, density functional theory was used to investigate possible descriptors for coordination and structural properties and stereoelectronic effects the of sulfonamides with Platinum. Some analyzes were carried out, including the analysis of the frontier molecular orbitals, the molecular electrostatic potential, the reactivity indices, and the evaluation of the structural and topological properties. Through analysis of the molecular electrostatic potential and frontier orbitals, it was agreed that the best region for platinum coordination is the nitrogen present in the functional amine group. The study of structural parameters prevented evaluating the behavior of sulfonamides before and after complexation with platinum, in which there was an increase in N–H and N–C bonds and a reduction in S=O and S–C bonds in the DMSO ligand, which could generate distortions in the structure of sulfonamide ligands. Based on topological properties, it was found that non-complexed sulfonamides (ligands) have stronger bonds (N–H and N–C) than in complexes.
