以[Zn（MeCO 2）2]·H2O、对苯二甲酸和2，2 ′-联吡啶为原料，经水热处理合成了一种配位聚合物[Zn（bpy）（tp）]（bpy）（1个; bpy = 2，2 ′-联吡啶，H2 tp =对苯二甲酸），其晶体属单斜晶系C2/c，Mr = 541.85，a = 15.388（11），B = 21.963（11），c = 7.670（8）A，β = 112.82（2）°，V = 2387（3）A3，Z = 4，Dc = 1.506 g·cm−3。X-射线单晶结构分析表明，1是一个三维网络与纳米级的通道由一维配位链通过C-H···O氢键和芳香插层构建。TGA和XRPD表明1的多孔网络非常稳定，而通道中的客体2，2 '-联吡啶分子是可去除的。化合物1在室温下的固态下显示出强的配体中心发射。（© Wiley-VCH Verlag GmbH & Co.

Hydrothermal treatment of a mixture of [Zn(MeCO2)2]·H2O, terephthalic acid, and 2,2′-bipyridine resulted in a coordination polymer [Zn(bpy)(tp)](bpy) (1; bpy = 2,2′-bipyridine, H2tp = terephthalic acid) which crystallizes in the monoclinic space group C2/c, Mr = 541.85, a = 15.388(11), b = 21.963(11), c = 7.670(8) A, β = 112.82(2)°, V = 2387(3) A3, Z = 4, Dc = 1.506 g·cm−3. An X-ray single-crystal structural analysis reveals that 1 is a three-dimensional network with nanosized channels constructed from one-dimensional coordination chains via C−H···O hydrogen bonds and aromatic intercalations. TGA and XRPD showed that the porous network of 1 is very stable while the guest 2,2′-bipyridine molecules in the channels are removable. Compound 1 shows a strong ligand-centred emission at room temperature in the solid state. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
