Structural, Hirshfeld surface and three-dimensional interaction energy studies of 2-(6-iodo-4-oxo-3,4-dihydroquinazolin-3-yl)ethanesulfonyl fluoride

In the crystal, molecules of the title compound, C 10 H 8 FIN 2 O 3 S, are connected through C—H...N and C—H...O hydrogen bonds, I...O halogen bonds, π–π stacking interactions between the benzene and pyrimidine rings, and edge-to-edge electrostatic interactions, as shown by the analysis of the Hirshfeld surface and two-dimensional fingerprint plots, as well as intermolecular interaction energies calculated using the electron-density model at the HF/3–21 G level of theory.
