测定了Ｏ，Ｏ（２，２′－联萘基）－Ｎ－（α－苯基乙基）膦酰胺（简称联萘酚膦酰胺，ＤＮＰＡ）ＲＳ体与乙醇形成的分子化合物晶体结构。晶体学数据为：Ｃ＿（２８）Ｈ＿（２２）ＮＯ＿３Ｐ·Ｃ＿２Ｈ＿５ＯＨ，Ｍｒ＝４９７．５，单斜晶系，Ｐ２＿１空间群，α＝９．３５９（２），ｂ＝１２．８０６（３），ｃ＝１１．６４１（Ａ），β＝１１１．６２（３）°，Ｚ＝２，Ｖ＝１２９４．０（５）（Ａ）３，Ｄｃ＝１．２７７ｇ／ｃｍ￣３，ＭｏＫａ（λ＝０．７１０７３Ａ）射线，μ＝０．１３６ｍｍ￣（－１），可观测数据３８７１个，Ｆ（０００）＝５２４，Ｒ＝０．０３５，Ｒｗ＝０．０４２。分子间以氢键相连接。ＲＳ体晶体结构与分子力学方法计算得到的ＳＳ体构象比较，发现这一对非对映体构象的差别由联萘基一边的构型决定。
The crystal structures of molecular compounds of O, O (2,2’-binaphthyl) -N- (α-phenylethyl) phosphonamide (DNPA) RS and ethanol were determined. The crystallographic data are: C_ (28) H_ (22) NO_3P · C_2H_5OH, Mr = 497.5, monoclinic system, P2_1 space group, α = 9.359 (2), b = 12.806 β = 111.62 (3) °, Z = 2, V = 1294.0 (A) 3, Dc = 1.277 g / cm 3, MoKa (λ = 0.71073A) rays, μ = 0.136 mm -1, observable data 3871, F (000) = 524, R = 0.035, Rw = 0.042. Intermolecular hydrogen bonding. RS body crystal structure and molecular mechanics calculated SS body conformation comparison found that the pair of diastereomer conformation differences determined by the binaphthyl side configuration.
