本文合成了两个新的同晶双核配合物[Ln（µ-NAP）4（NAP）2（phen）2] · H2O（1）和（2）（Ln = Eu，Tb，NAP = N-乙酰基-N-苯基甘氨酸; phen = 1，10-菲咯啉），并通过红外光谱、元素分析和X射线晶体学对其进行了表征。这些化合物以三斜晶系形式结晶，空间群为P_（11），a = 11.7519（11），B = 13.4293（12），c = 14.0686（13）π，V = 1992.7（3）π 3，Z = 1。单晶X-射线结构分析表明，化合物1为双核结构，通过自互补双氢键和芳香π-π相互作用组装成三维超分子网络。并对1和2的荧光性质进行了讨论。
In this study, two new isomorphic binuclear compounds, [Ln(µ-NAP)4(NAP)2(phen)2] · H2O (1) and (2) (Ln = Eu, Tb, NAP = N-acetyl-N-phenylglycinate; phen = 1,10-phenanthroline), have been synthesized and characterized by infrared spectroscopy, elemental analysis, and X-ray crystallography. These compounds crystallize in a triclinic form with space group Pī with a = 11.7519(11), b = 13.4293(12), c = 14.0686(13) Å, V = 1992.7(3) Å3, and Z = 1. Single-crystal X-ray structural analysis reveals that 1 is binuclear, assembled into a 3-D supramolecular network with self-complementary double hydrogen-bonding interactions and aromatic π–π interactions. Fluorescence properties of 1 and 2 are also discussed.
