Article abstract of DOI:10.1007/BF01666729

1,3,5-triphenyl-1,5-pentanedione, C23H20O2, has been prepared and characterized by spectroscopic methods and single crystal X-ray analysis.Crystals are monoclinic, space group P2₁/n, a = 28.124(4), b = 5.997(1), c = 10.434(1) Angstroem, β = 98.42(1) deg, Z = 4.The structure has been refined to a final R-value of 0.040 for 1625 reflections with F_o > 3?(F_o).The compound contains the two carbonyl groups in a mutually cis arrangement.KEY WORDS: C23H20O2, diketone, cis arrangement.
