| 摘要: 通过固定银离子、2，2′-联吡啶-4，4′-二羧酸(H2bina)和1，3-二(4-吡啶基)丙烷(bpp)等原料配比和反应时间，在不同反应温度下分别制备了基于Ag2簇单元的配合物{[Ag2(bpp)2][Ag2(bina)2(H2O)2]·6H2O}n (1)和含Ag4簇的配合物{[Ag4(bpp)2(bina)2(H2O)2]·4H2O}n (2)。结构研究与性质测试对比表明这两个类三明治型配合物不仅晶体学参数、银离子配位环境、柔性配体构象、客体水分子数目发生了变化，而且荧光及热稳定性各异。 |

| Abstract: The solution reactions of Ag(Ⅰ) with 2,2′-biisonicotinic acid (H2bina) in the presence of 1,3-di(4-pyridyl)propane (bpp) at different temperature generate two sandwich-like complexes, {[Ag2(bpp)2][Ag2(bina)2(H2O)2]·6H2O}n(1, based on Ag2 clusters ) and {[Ag4(bpp)2(bina)2(H2O)2]·4H2O}n (2, based on Ag4 clusters). Structural and property studies reveal two sandwich-like complexes have different crystallographic parameters, coordination environment of Ag(Ⅰ) atoms, the conformations of flexible ligands and the number of solvent molecules, as well as their fluorescence spectrum and thermal stability.
