A series of 1,2,3,5-tetraarylpentane-1,5-diones (9-23) were synthesised by simple one-pot method and characterized by FT-IR, ¹H NMR, ¹³C NMR and mass spectral techniques. The structure of 3-(4-fluorophenyl)-1,2,5-triphenylpentane-1,5-dione (10) was determined by single crystal X-ray diffraction analysis. The compound 10 crystallize in monoclinic crystal system, in C2/c space group. The torsional angle between the two keto groups was found to be -29.50. The C(23)C(22)C(15)C(8)C(7) chain is almost planar with "W" conformation and observed maximum deviation is 0.122 ? for C(15) from the C(23)/C(22)/C(15)/C(8)/C(7) plane.
