is stabilized by interatomic hydrogen bond interactions between the doubly bonded phosphoryl O atom and the hydroxyl H atom which link the molecules into chains along the [011] plane of the unit cell.Index AbstractThe title compound, diisopropyl hydroxy(4-methoxyphenyl)methylphosphonate, was synthesized by the reaction of 4-methoxybenzaldehyde and diisopropyl phosphite. Its structure was determined
摘要 由4-甲氧基苯甲醛与亚磷酸二异丙酯反应合成标题化合物C14H23O5P。其结构是用 X 射线晶体学、核磁共振、质谱和元素分析 (EA) 技术确定的。该晶体属于单斜晶系,空间群 P 21/n,具有以下晶体学参数:a = 10.529 (2) Å, b = 8.424 (2) Å, c = 19.448 (4) Å, α = 90°, β = 105.2 (3)°, γ = 90°, μ = 0.180 mm−1, V = 1664.1 (6) Å3, Z = 4, Dx = 1.207 mg/mm3, F (000) = 648, T = 293 (2) K , 2.00° ≤ θ ≤ 25.50°。对于 1933 年的反射,I > 2σ (I) 的最终残余因子为 0.049。晶体堆积通过双键磷酰基 O 原子和羟基 H 原子之间的原子间氢键相互作用稳定,这些相互作用将分子连接成沿晶胞 [011]
