摘要：

The crystal and molecular structure of 3-benzoyl-6-phenylhex-5-ene-2,4-dione has been determined at 121 K by X-ray crystallographic methods using 2782 reflections measured by counter methods. The crystals are monoclinic, space group P2(1)/n (No. 14). The structure was refined to a conventional R-Factor of 0.046. The enol ring is clearly asymmetric, and the enol hydrogen is bonded to the oxygen atom next to the olefinic double bond. The molecular conformation and the intermolecular interactions are discussed.
