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。
Two kinds of complexes [Zn2 (npa) 2 (Im) 4] (1) and [Cd2 (npa) 2 2,2’-bipy) 2 (H2O) 2] .2H2O (2) (npa2- = 3-nitrophthalate, Im = imidazole, 2,2’-bipy = 2,2’-bipyridine ). The crystal structure of the complex was characterized by elemental analysis and FTIR. The crystal structure of the complex was characterized by single crystal X-ray diffraction. The thermal stability of complexes 1 and 2 was measured. Two complexes are dual-core molecules, with M2C8O4 fourteen yuan macrocyclic structure. The binuclear unit of the complex 1 formed a 3D network structure through intermolecular hydrogen bonding, and the binuclear unit of the complex 2 formed a 2D layered structure through intermolecular hydrogen bonding and π-π stacking.
