摘 要:The new compound 1,4,7,10-tetrakis-(2-(2,3-difluorophenyl) ethyl) -1,4,7,10-tetra-zacyclododecane 2 has been synthesized and structurally characterized by single-crystal X-ray diffraction. The molecule turned into diamond crystals grown from CH3CN by slow diffusion at room temperature. It crystallizes in the triclinic system,space group P1^- with a = 9.543(2) ,b = 10.507(3) ,c = 10.734(3) A,α = 60.979(3) ,β = 81.870(4) ,γ = 84.279(4) o,V = 931.1(4) 3,Z = 1,Dc = 1.307 g/cm^3,C40H44F8N4,Mr = 732.79,F(000) = 384,μ = 0.105 mm^-1,T = 296(2) K,MoKa radiation(λ = 0.71073) ,R = 0.0494 and wR = 0.0989 for 1589 observed reflections with I 〉 2σ(I) . Hydrogen bonds and C-H···π stacking interactions in 2 contribute to a supramolecular structure. Moreover,compound 2 has been determined by ^1H NMR,^13C NMR,MS,IR spectra and elemental analysis.
