摘要
0引言
近年来,利用弱的非共价作用力例如氢键、π-π堆积以及静电作用来组装结构新颖的超分子配位聚合物已成为配位化学和超分子化学的研究热点之一。其中芳香羧酸的稀土超分子配位聚合物由于其优良的发光性能和在催化、分离和气体储存等方面展示了广阔的应用前景以及新颖的结构而倍受材料化学和超分子化学工作者关注。
One Ytterbium coordination polymers,{[Yb(APA)(HAPA)(phen)]·H2O}n,(H2APA=5-aminoisophthalic acid,phen =1,10-phenanthroline) have been synthesized by hydrothermal method,and characterized by single crystal X-ray diffraction,elemental analysis and IR spectra. Crystallographic data show that the title complex crystallize in a monolinic system,space group P21/c with a=1.028 4(4) nm,b=2.126 3(7) nm,c=1.253 2(4) nm,β= 103.726(4)°,V=2.662 1(16) nm3,Z=4,Dc=1.823 Mg·m^-3. H2APA ligands exhibit two kinds of coordination modes and link the Yb3+ ions to a 1D chain structure,which is further linked to form 3D supramolecular structure via rich O-H…O,O-H…N,N-H…O and C-H…O hydrogen bondings. The thermogravimetric analysis was carried out to examine the thermal stability of the titled complex. CCDC:745208.
