| 摘要: 室温下，AgNO3、4，4′-联吡啶(bpy)/1，2-二(4-吡啶基)乙烯(dpe)与联苯二甲酸(H2da)在乙酸/乙醇水溶液中反应数周后分别得到块状晶体[Ag2(bpy)2(Hda)2](HAc)2·2H2O (1)和[Ag2(dpe)2(da)]·4H2O (2)。上述两种晶体均包含无限扩展的一维阳离子链[AgL]∞(L=bpy和dpe)，而穿插其中的有机阴离子da2-起到了平衡电荷的作用。结晶水分布于离子链之间并形成氢键，对晶体堆积起到了定位作用。UV/Vis/NIR漫反射光谱测定结果表明化合物1和2的光学能隙Eg均约为3.3 eV。 |

| Abstract: The reaction of AgNO3, 4,4′-bipyridine (bpy)/flexible 1,2-di(4-pyridyl)ethylene (dpe), diphenic acid (H2da) in acetic acid/alcohol aqueous solution produces, respectively, block-like crystals of [Ag2(bpy)2(Hda)2](HAc)2 ·2H2O (1), and [Ag2(dpe)2(da)]·4H2O (2) at room temperature. Both the above-stated compounds consist of parallel 1D infinite cationic chains, [AgL]∞ (L=bpy and dpe), interspersed with organic da2- anions which play the role of charge compensation in the crystal structure. The lattice water molecules are situated among these chains, and stabilized by rich hydrogen-bonding interactions, playing a role in the orientation of the da2- in the crystal packing. Optical absorption properties and band gaps of title compounds were determined with UV/Vis/NIR diffuse reflectance spectra, and the results show that the Eg can be assessed at 3.3 eV for both compound 1 and 2.
