| 摘 要： | 以Ln2O3(Ln=Nd和La),2,2′-联吡啶-3,3′-二羧酸(bpdc),4,4′-联吡啶(bpy)为原料,采用溶剂热法合成了2个具有二维骨架结构的无机-有机杂化材料Nd2(bpdc)3(H2O)2]·bpy·4H2O(1)和La2(bpdc)3(H2O)4]·4H2O(2),通过IR和X-射线单晶衍射分析等手段对其结构进行了表征。晶体1属于单斜晶系,C2/c空间群,晶胞参数a=3.3104(7)nm,b=0.74812(15)nm,c=1.9848(4)nm,β=104.75(3)°。晶体2属于单斜晶系,C2/c空间群,晶胞参数a=2.6749(5)nm,b=0.71165(14)nm,c=2.0542(4)nm,β=92.70(3)°。在这2个配位聚合物中,晶体中的结晶水沿着b轴呈现一维无限有序排列,将化合物中二维的金属有机骨架通过氢键相连进而形成了三维超分子结构。

| Abstract: | Two new lanthanide MOF compounds,Nd2(bpdc)3(H2O)2]·bpy·4H2O (1) andLa2(bpdc)3(H2O)4]·4H2O (2) (bpdc=2,2'-bipyridine-3,3'-dicarboxylate,bpy=4,4'-bipyridine) have beeh synthesized under hydrothermal conditions.The crystal structure analysis indicates that both compounds crystallize in monoclinic system,space group C2/c.the crystal cell parameters for compound 1 are a=3.310 4(7) nm,b=0.748 12(15) nm,c=1.984 8(4) nm,β=104.75(3)°,and for compound 2 are a=2.674 9(5) nm,6=0.711 65(14) nm,c=2.054 2(4) nm,β=92.70(3)°.In compound 1,the Nd(Ⅲ) ions are bridged by bpdc ligands with two coordination modes to form a two-dimensional neodymium MOF layer.The layers ale connected by one-dimensional water chains and bpy molecules through rich hydrogen-bonding interactions to build up a three-dimensional supramoleculal structure.The crystal structure of 2 is constructed by the layered lanthanum MOFs and the interlayer water chains through hydrogen bonding interactions. |
