The title compound, C16H9F2NO2, was synthesized, characterized by spectroscopic techniques (FT-IR, UV-visible, 1H NMR, TGA) and finally the three dimensional structure was confirmed by X-ray diffraction studies. The title compound is thermally stable upto 230 °C and shows the UV absorption peak at 325 nm. In the crystal structure, molecules are connected through intermolecular hydrogen bonds of the type O-Hâ â â O and short contacts (C-Fâ â â Ï and Ïâ â â Ï). An intramolecular hydrogen bonds of the type C-Hâ â â O and C-Hâ â â N were observed. The short contacts are analyzed and visualized using Hirshfeld surfaces computational methods. Intercontacts of the type Hâ â â H (25.9%), Fâ â â H (22.5%), Câ â â H (12.4%), Hâ â â O (10%), Fâ â â O (3.1%), Fâ â â C (3.4%), Oâ â â C (2.5%), Nâ â â H (2.1%), Câ â â N (2.5%), Fâ â â F (0.2%), Oâ â â O (0.6%) and Nâ â â N (0.3%) were observed and respective 2D fingerprint plots were plotted.
