| 摘要: 以3-硝基邻苯二甲酸和咪唑及2，2’-联吡啶为配体构筑了2种配合物[Zn2（npa）2（Im）4]（1）和[Cd2（npa）2（2，2’-bipy）2（H2O）2]·2H2O（2）（npa2-=3-硝基邻苯二甲酸根，Im=咪唑，2，2’-bipy=2，2’-联吡啶）。用元素分析、红外光谱对其进行了表征，并用单晶X-射线衍射测定了配合物的晶体结构；测定了配合物1和2的热稳定性。2个配合物均为双核分子，具有M2C8O4十四元大环结构。配合物1的双核单元通过分子间氢键形成3D网络结构，配合物2的双核单元通过分子间氢键和π-π堆积形成2D层状结构。 | |

| Abstract: Two complexes [Zn2(npa)2(Im)4] (1) and [Cd2(npa)2(2,2'-bipy)2(H2O)2]·2H2O (2) (H2npa=3-nitrophthalic acid, Im=imidazole, 2,2'-bipy=2,2'-bipyridine) were constructed by the use of 3-nitrophthalic acid and imidazole or 2,2'-bipyridine, respectively. The complexes were characterized by elemental analysis, IR, and the crystal structures were determined by single X-ray diffraction. The thermal stabilities of the complexes were studied by thermal gravimetric analysis. The two complexes are dinuclear structures, and both contain M2C8O4 14-membered rings. The dinuclear units extend to 3D network through intermolecular hydrogen bonding interactions for complex 1, while a 2D sheet structure is formed for complex 2 by hydrogen bonding and π-π stacking interactions. | |
