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 complexes were synthesized by the hydrothermal method with 2,2’-bipyridine-3,3 ’, 6,6’-tetracarboxylic acid (H4bptc) as ligands and their molecular formulas were [Co2 (H2bptc) 2 (H2O) 4] · bpe · 9H2O (1), [Ni2 (H2bptc) 2 (H2O) 4] · bpe · 9H2O (2), [Ni2 (H2bptc) 2 0.5 bpp · 7H2O (3) (bpe = 1,2-bis (4-pyridyl) ethylene, bpp = 1,2-bis (4-pyridyl) ethane). The crystal structure of the compounds was characterized by FTIR and X-ray single crystal diffraction. The thermal stability of these three complexes was tested. Compounds 1 to 3 are complexes of mononuclear structures, all of which form a three-dimensional supramolecular structure by intermolecular hydrogen bonding.
