| 摘要: 以2,2'-联吡啶-3,3',6,6'-四羧酸(H4bptc)为配体,通过水热合成的方法与过渡金属盐合成了3个配合物,其分子式分别为[Co2(H2bptc)2(H2O)4]·bpe·9H2O(1),[Ni2(H2bptc)2(H2O)4]·bpe·9H2O(2),[Ni2(H2bptc)2(H2O)4]·0.5bpp·7H2O(3)(bpe=1,2-二(4-吡啶基)乙烯,bpp=1,2-二(4-吡啶基)乙烷)。用红外光谱,X-射线单晶衍射对化合物的晶体结构进行了表征,并对这3个配合物的热稳定性进行了测试。化合物1~3为单核结构的配合物,它们均通过分子间氢键形成三维超分子结构。 |

| Abstract: Three transition metal complexes, namely, [Co2(H2bptc)2(H2O)4]·bpe·9H2O (1), [Ni2(H2bptc)2(H2O)4]·bpe·9H2O (2), [Ni2(H2bptc)2(H2O)4]·0.5bpp·7H2O (3) (H4bptc=2,2'-bipyridine-3,3',6,6'-tetracarboxylic acid, bpe=1,2-di(4-pyridyl)ethylene, bpp=1,2-di(4-pyridyl) ethane) have been synthesized under hydrothermal conditions and structurally characterized by infrared spectra, thermogravimetric analyses and single crystal X-ray diffraction. Compounds 1~3 are the mononuclear units and extended further to generate the three-dimensional supramol-ecular architectures by strong hydrogen-bonding interactions, respectively.
