The compound 1-(3,4-dimethoxyphenyl)-3-(4-flurophenyl)-propan-1-one (DFPO) was synthesized by Claisen-Schmidt condensation reaction and the single crystals were obtained by slow evaporation method. Three-dimensional structure was confirmed by single crystal X-ray diffraction method and exhibiting the triclinic crystal system with space group P-1. The crystal structure is stabilized by C-H center dot center dot center dot O intermolecular and weak interactions. Computed molecular geometry has been obtained by density functional theory (DFT) and compared with experimental results. The spectra of both FT-IR in the range (4000-400 cm(-1)) and FT-Raman (3500-50 cm(-1)) of DFPO were recorded experimentally and computed by (DFT) using B3LYP/6-311G (d,p) as basis sets. Intramolecular charge transfer has been scanned using natural bond orbital (NBO) analysis and revealed the various contribution of bonding and lone pair to the stabilization of molecule. Nonlinear optical activity (NLO) of the title compound has been determined by second harmonic generation (SHG) and computed using OFT method. Hyperpolarizability, HOMO-LUMO energy gap, hardness, softness electronegativity and others Global reactivity descriptors of DFPO has been calculated and revealed complete picture of chemical reactivity of DFPO. Hirshfeld surface analyses were applied to investigate the intermolecular interactions and revealed that more than two-thirds of the inter contacts are associated with O center dot center dot center dot H, C center dot center dot center dot H and H center dot center dot center dot H interactions. Docking studies of DFPO showed inhibition of Vascular endothelial growth Factor human receptor (VEGFR-2) signalling pathway, which indicates DFPO as anti-angiogenesis, that play pivotal role in cancer, so we suggest it for clinical studies to evaluate its potential to treat human cancers.
