以柱状二齿配体吡嗪和对苯二甲酸(H2bdc)为混合配体,在溶剂热条件下与过渡金属离子Co2+组装反应,得到一个新型金属有机骨架化合物[Co3(Hbdc)2(bdc)2]·4DMF·2H2O(1).通过红外光谱、热重和单晶X射线衍射等分析手段对其进行了表征与分析.结果表明,化合物1的晶体属单斜晶系,空间群为C2/c.中心Co原子通过不同配位模式的bdc配体相连构成三维开放结构,孔道内填充了结晶的DMF和水分子.
A new type of metal-organic framework compound [Co3 (Hbdc) 2 (bdc)] was synthesized by the reaction of transition metal ions Co2 + with the bidentate ligand pyrazine and terephthalic acid (H2bdc) 2] 4DMF · 2H2O (1) .It was characterized and analyzed by IR, TG and single crystal X-ray diffraction.The results show that the crystal of compound 1 is monoclinic and the space group is C2 / c. The central Co atoms form 3D open structures through the bdc ligands with different coordination modes, and the channels are filled with crystalline DMF and water molecules.
