1-(2-Hydroxyphenyl)-3-phenyl-1,3-propanedione crystallizes in the triclinic space group$$Pbar 1$$(a=5.4233(5),b=13.910(1),c=17.036(1) Å, α=68.311(6), β=80.854(7), γ=78.760(8)°) as two independent enolic tautomers in which the hydroxyl and phenolic protons are hydrogen bonded to the ketonic oxygen atom. The structure was refined toR=0.039 for 2085I≥3σ(I) reflections. 1-(1,3-Benzodioxol-5-yl)-3-(2,4-dimethoxyphenyl)-1,3-propanedione, which belongs to the triclinic$$Pbar 1$$space group (a=7.3990(7),b=8.1239(5),c=14.004(1) Å, α=86.673(6). β=88.574(7), γ=64.885(7)°) also exists in the enolic form. The structure was refined toR=0.040 for 1564I≥3σ
