摘要
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 metal-organic framework [Co3（Hbdc）2（bdc）2]· 4DMF· 2H2O （1） was synthesized through the self-assembly reaction between the mixed ligands （pyrazine, H2bdc） and transition metal ion Co2＋under the solvothermal condition .Compound 1 was characterized by IR spectroscopy , TG and single-crystal X-ray diffrac-tion.The result showed that the crystal belonged to monoclinic system with C 2/c space group.The Co centers are bridged by bdc ligands with different coordination modes , generating a three-dimensional open framework , in which the crystallized DMF and water molecules are involved .
