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。
Three transition metal complexes, namely, [Co2(H2bptc)2(H20)4] "bpe'9H20 (1), [Ni2(H2bptc)2(H20)4]bpe "9H20 (2), [Ni2(H2bptc)2(H20)4] .0.5bpp "7H20 (3) (H4bptc=2,2'-bipyridine-3,3',6,6'-tetracarboxylic acid, bpe=1,2-di(4-pyridyl)ethylene, bpp=l,2-di(4-pyridyl) ethane) have been synthesized under hydrothermal conditions andstructurally 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.
