| Abstract: 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. |
