HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

The synthesis and investigation of a new biologically active derivative of dihydropyrimidine are reported. The structure of the synthesized compound was investigated by X-ray single crystal diffraction method. In order to understand the molecular interactions, the Hirshfeld surface and contacts enrichment analyses were performed. The crystal packing is mainly stabilized by strong N-H…O hydrogen bonds and aromatic cycle stacking. Among the different types of oxygen atoms, the most electronegative had the highest propensity to form H-bonds. Biological activity of the synthesized compound was studied against E.coli, P. aeruginosa and S. aureus bacteria.
