超分子化合物[H2(C18H18N2O2)](SCN)由Fe(NO3)3·9H2O,KSCN和1,4-双(4-吡啶基甲基苯基醚)反应得到。通过X射线衍射仪测得该化合物是通过N┈H—N,S┈H—C(C5H5N)及S┈H—C(亚甲基CH2)三种氢键而形成的二维平面网状结构。用Z扫描法对该超分子在DMF溶液中的三阶非线性光学性质进行研究，发现它具有强的三阶非线性折射性能，三阶非线性超极化率X^(3)=6.27×10^-12esu.

A novel supramolecular compound [H2(C18H18N2O2)] (SCN)2 was obtained by reaction of Fe(NO3)3 and KSCN with C18H18N2O2. This compound has a two-dimensional network structure, in which there exists three types of hydrogen bonds: N┈H—N,S┈H—C(CH2) and S┈H—C(CH). The structure of this supramolecule was established by X-ray diffraction: triclinic, group space P1, a=0.69115(14) nm, b=0.86367(17) nm, c=0. 91352(18)nm, α=84.03(3)°, β=78.65(3)°, γ=81.87(3)°, V=0.52764(18) nm^3, Z=2, R=0.0670. This compound in DMF solution shws strong third- order non-linear optical properties with a calculated χ^(3) of 6.27× 10^-12 esu.
