在乙腈溶液中合成了标题化合物，（C(34)H(54)N2O10）[Eu（NO3）5]（C(34)H(52)H2O(10)＝1，2-二（2，3-苯并-10－氮杂-15-冠-5－N-乙氧基）乙烷）并用X射线衍射分析测定了它的结构。该晶体属单斜晶系，P21／c空间群，晶胞参数：a＝1．1801（2）nm，b＝2．3560（5）nm，c＝1．7025（3）nm，β=99．67（3）°。V＝4．6662（16）nm’，Z＝4，Dc=1．581g·cm(－3)。Eu(3+)与5个NO3的10个O配位。大环化合物上无论是O还是N都未与Eu(3+)成键。
The title compound was synthesized in acetonitrile solution. The molar ratio of (C (34) H (54) N2O10) [Eu (NO3) 5] -benzo-10-aza-15-crown-5-N-ethoxy) ethane) and its structure was determined by X-ray diffraction analysis. The crystal belongs to the monoclinic space group P21 / c with unit cell parameters of a = 1.1801 (2) nm, b = 2.3560 (5) nm and c = 99.67 (3) °. V = 4.6662 (16) nm ’, Z = 4, Dc = 1.581 g-cm (-3). Eu (3+) is coordinated with 10 O of 5 NO3. Macrocyclic compounds have neither O nor N bond with Eu (3+).
