摘要：

5-Hydroxy-2-(hydroxymethyl)-4H-pyran-4-one, C6H6O4, M(r) = 142.1, monoclinic, P2(1)/n, a = 3.8323 (8), b = 18.409 (6), c = 8.505 (4) angstrom, beta = 96.56-degrees, V = 596.1 angstrom 3, Z = 4, D(x) = 1.58, D(m) = 1.57 g cm-3, lambda(Cu K-alpha) = 1.54178 angstrom, mu = 10.62 cm-1, F(000) = 296, T = 300 K, final R = 0.045 for 676 observed reflections. The pyran ring is planar (CHI-2 = 7.81). The molecules are linked by an O-H...O hydrogen bond [1.87 (3) and 2.08 (4) angstrom].
