Synthesis,Crystal Structure and Characterizations of A Novel Open-Framework Lanthanide Imidazoledicarboxylate

LI Hui-duan

摘要: 采用H2 O/DM F混合溶剂热技术，选择咪唑羧酸衍生物和草酸混合配体与稀土金属铽配位合成了具有开放骨架结构的稀土咪唑羧酸配合物：[Tb（HpyimdC）（C2O4）0.5（H2O）]·（H2O）3（配合物1）．X 射线单晶衍射等测试结果表明配合物1结晶在单斜晶系，C2/c空间群（No.15）；草酸与稀土铽螯合配位形成一维 z igz ag链，再通过异位吡啶基咪唑羧酸的配位作用连接形成配合物1的三维开放骨架结构，沿 y，z轴具有穿插超大孔道，客体分子位于孔道中．
