四种新型的Zn Ⅱ配位聚合物[Zn（btc）0.5（H2O）]n（1），{[Zn（btc）0.5（4，4'-bpy）0.5（H2O）]·1.5H2O}n（2），{[Zn2（H2btc）2（4，4 '-bpy）4]·H2O}n（3），[Zn（H2 btc）（bpe）]n（4）[H4 btc =联苯-3，3'，4，4 '-四羧酸，4，4'-bpy = 4，4 '-联吡啶，bpe = 1，2-双（4-吡啶基）乙烷]。单晶X-射线结构分析表明，这四种聚合物表现出不同的新颖的双层结构。配合物1具有双层结构，其中两个螺旋层进一步由（btc）4-配体柱撑成二维（2D）双层网络。配合物2是一种特殊的二维双层超分子结构，由两个单层网络通过氢键相互作用形成。配合物3是由一维{[Zn 2（H2 btc）2（4，4 '-bpy）4]·H2O}n聚合物形成的二维超分子双层网络。配合物4是一个二维的双层结构，其中两个褶皱的单层由（H2 btc）2-的μ2-羧基连接。潜水员...
Four novel ZnII coordination polymers, [Zn(btc)0.5(H2O)]n (1), {[Zn(btc)0.5(4,4‘-bpy)0.5(H2O)]·1.5H2O}n (2), {[Zn2(H2btc)2(4,4‘-bpy)4]·H2O}n (3), [Zn(H2btc)(bpe)]n (4) [H4btc = biphenyl-3,3‘,4,4‘-tetracarboxylic acid, 4,4‘-bpy = 4,4‘-bipyridine, and bpe = 1,2-bis(4-pyridyl)ethane], have been synthesized by hydrothermal reactions. Single-crystal X-ray structural analysis reveals that the four polymers exhibit different novel bilayer architectures. Complex 1 possesses a bilayer structure in which two helical layers are further pillared by (btc)4- ligands into a two-dimensional (2D) bilayer network. Complex 2 is an unusual 2D double-layered supramolecular motif generated by hydrogen bonding interactions of two single-layered networks. Complex 3 displays a 2D supramolecular bilayer network formed by the one-dimensional {[Zn2(H2btc)2(4,4‘-bpy)4]·H2O}n polymer. Complex 4 features a 2D double-layered framework in which two puckering single layers are linked by μ2-carboxylato groups of (H2btc)2- anions. The diver...
