C5H10O4, Mr = 134.31, monoclinic, P2(1), a = 11.670 (2), b = 6.177 (3), c = 10.704 (2) A, beta = 115.11 (2) degrees, V = 698.7 (4) A3, Z = 4, Dm = 1.26, Dx = 1.28 g cm-3, Cu K alpha, lambda = 1.54178 A, mu = 9.69 cm-1, F(000) = 288, room temperature, R = 0.046 for 1047 reflections with [Fo[ greater than 3 sigma(F). There are two independent molecules of the title compound in the crystal. No twofold symmetry is observed in the tetrahydrofuran rings. Hydrogen bonds between water molecules and carboxylic acid groups stabilize the crystal structure.
C5H10O4，Mr = 134.31，单斜晶系，P2(1)，a = 11.670 (2)，b = 6.177 (3)，c = 10.704 (2) Å，β = 115.11 (2)°，V = 698.7 (4) ų，Z = 4，Dm = 1.26，Dx = 1.28 g cm⁻³，Cu Kα，λ = 1.54178 Å，μ = 9.69 cm⁻¹，F(000) = 288，室温，对于1047个[Fo]大于3σ(F)的反射，R = 0.046。晶体中有两个独立的标题化合物分子。在四氢呋喃环中未观察到二重对称性。水分子与羧酸基团之间的氢键稳定了晶体结构。
