Orthorhombic form of 6-phenylhex-5-ene-2,4-dione

A. F. Arrieta and A. Mostad

Abstract: The title compound, C₁₂H₁₂O₂, crystallizes in at least two polymorphic forms, one monoclinic and the other orthorhombic. In the orthorhombic polymorph, the enol group is asymmetric with the H atom bonded to the O atom closest to the most electronegative substituent, and the molecule displays the longest possible conjugation. The molecular packing is dominated by weak C-HO interactions.
