| 摘 要： | The title compound 3,9-bis(pyridin-2-yl)-2,4,8,10-tetraoxaspiro5.5]undecane 4(C17H18N2O4) has been synthesized by the reaction of 2,2-bis(hydroxymethyl)propane-1,3-diol with pyridine-2-carbaldehyde in the presence of p-toluenesulfonic acid,and characterized by IR,1H-NMR and X-ray single-crystal diffraction.The crystal belongs to monoclinic system,space group C2/c with a = 25.133(2),b = 5.7219(5),c = 21.942(2) ,β = 99.145(2)°,V = 3115.3(5)3,Z = 8,Dc = 1.340 g/cm3,Mr = 314.33,F(000) = 1328,μ = 0.097 mm-1,MoKa radiation(λ = 0.71073),R = 0.0352 and wR = 0.1022 for 2486 observed reflections with I > 2σ(I).X-ray analysis reveals that the two 1,3-dioxane rings passing through the central spiro-C atom both adopt chair conformation.Intermolecular C-H…π,C-H…O and C-H…N weak interactions link the molecules to form a three-dimensional samdwich,which are effective in the stabilization of the crystal structure.
