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(Had)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.UVNis/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3.3eV.

The reaction of AgN03, 4,4'-bipyridine (bpy)/flexible 1,2-di (4-pyridyl)ethylene (dpe), diphenic acid (HZda) in acetic acid/alcohol aqueous solution produces, respectively, block-like crystals of [Ag2(bpy)2(Hda)2](HAc)2 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 dal- in the crystal packing. Optical absorption properties and band gaps of title compounds were determined with UVNis/NIR diffuse reflectance spectra, and the results show that the Eg can be assessed at 3.3 eV for both compound 1 and 2.CCDC: 768737, 1;768736, 2.
