以吡嗪2,3-二羧酸为配体制备得到了两个新型氢键组装的异核金属化合物{[Mg(H2O)6][Cu2(Pzdc)2]·4H2O}n(1)和{[Mg(H2O)6][Co2(HPzdc)6]}n(2)。单晶X射线衍射分析表明,化合物(1)为一维链状聚合物,化合物(2)则为独立分子。通过水分子、阳离子和阴离子间大量的氢键作用进而将化合物(1)和化合物(2)连接成为三维和二维的超分子化合物。另外,利用元素分析、红外光谱、粉末X射线衍射和热分析技术对化合物进行了表征。 Two new hydrogen-bonded heteronuclear compounds {[Mg (H2O) 6] [Cu2 (Pzdc) 2] · 4H2O} n (1) and {[Mg (H2O) 6] [Co2 (HPzdc) 6]} n (2). Single crystal X-ray diffraction analysis shows that compound (1) is a one-dimensional chain polymer and compound (2) is a separate molecule. The compound (1) and the compound (2) are connected into three-dimensional and two-dimensional supramolecular compounds through a large number of hydrogen bonds between water molecules, cations and anions. In addition, the compounds were characterized by elemental analysis, infrared spectroscopy, powder X-ray diffraction and thermal analysis.
