摘要：

The crystal and molecular structure of the title compound: C13H10O4, M(r) = 230.22, determined by single crystal X-ray diffraction is reported. Crystals are monoclinic, space group P2(1)/c, a = 3.991(3), b = 21.381(4), c = 12.289(4) angstrom, b = 91.15(1)-degrees, V = 1048(1) angstrom3, z = 4, D(x) = 1.46 Mg m-3, lambda(Mo Kalpha) = 0.7107 angstrom, m = 0.87 mm-1, F(000) = 480, T = 298 K. The structure was solved by direct methods and the final R value is 0.071 (wR = 0.055) for 795 independent observed reflections. The cyclohexadienic moiety of the molecule adopt a twist conformation.
