【 摘 要 】

The molecular structures of (E)-non-2-enoic acid (C9) and (E)-dec-2-enoic acid (C10) are reported. The title compounds were crystallized by slow evaporation of ethanolic solutions at −30 °C. C9 crystallizes in the monoclinic space group P2₁/c and C10 in the triclinic space group P-1, each with 4 molecules in the unit cell. The unit cell parameters for C9 are: a = 10.6473(4) Å, b = 5.2855(2) Å, c = 17.0313(7) Å; β = 106.0985(10)° and V = 920.87(6) ų. The unit cell parameters for C10 are: a = 4.1405(2) Å, b = 15.2839(6) Å, c = 17.7089(7) Å; α = 68.3291(11)°, β = 83.3850(13)°, γ = 85.0779(12)° and V = 1033.39(8) ų.
