Abstract
The crystal structure of Luvangetin (C15H14O4) has been determined from three-dimensional X-ray diffraction data. The compound crystallizes in the triclinic space group P[unk] with unit cell parameters a = 8.391(1) Å, b = 11.617(10) Å, c = 7.461(10) Å, α = 99.014°, β = 116.476°, γ = 75.886°, cell volume = 630.23 Å3, dc = 1.36 g/ml, dm = 1.32 g/ml, μ(CuKα) = 8.27/cm, Z = 2. The gross structure was determined from 835 observed reflections by direct methods which on refinement yielded R = 0.052. The hydrogen atoms were located from difference syntheses. There are no hydrogen bonds in the crystal. The structural relationships between the rings are discussed.
