Two unusual metal-organic frameworks {[Ag(2)(Hbtc)(bpy)(2)]·(H(2)O)(2)}(n) (1), {[Ag(3)(btc)(bpy)(3)(H(2)O)]·(H(2)O)(7)}(n) (2) (H(3)btc = 1,2,3-benzenetricarboxylic acid, bpy = 4,4'-bipyridine) have been synthesized and characterized by single crystal X-ray diffraction. Complex 1 features an infinite 1D→1D tubular intertwinement network, while complex 2 exhibits a double ladder structure which contains rare winding water chains. Both infinite 1D→1D tubular chains in complex 1 and double ladder in 2 are mutually interconnected by hydrogen bonding and π···π stacking interactions into three-dimensional (3D) supramolecular networks. In addition, thermogravimetric analysis, powder X-ray diffraction (XRD), and photoluminescent behavior of the complexes have also been investigated.
两个不寻常的金属有机骨架 {[Ag(2)(Hbtc)(bpy)(2)]·(H(2)O)(2)}(n) (1), {[Ag(3)(btc)(bpy)(3)(H(2)O)]·(H(2)O)(7)}(n) (2) (H(3)btc = 1,2,3-苯三甲酸，bpy = 4,4'-联吡啶)} 已通过单晶 X 射线衍射合成并进行了表征。配合物 1 具有无限的 1D→1D 管状互穿网络，而配合物 2 则具有罕见的缠绕水链的双梯状结构。1 中无限的 1D→1D 管状链和 2 中的双梯相互通过氢键和 π···π 堆积相互作用连接成三维 (3D) 超分子网络。此外，还研究了配合物的热重分析、粉末 X 射线衍射 (XRD) 和光致发光行为。
