One Ytterbium coordination polymers, {[Yb(APA)(HAPA)(phen)]center dot H2O}(n), (H(2)APA=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 P2(1)/c with a=1.028 4(4) nm, b=2.126 3(7) nm, c=1.253 2(4) nm, beta=103.726(4)degrees, V=2.662 1(16) nm(3), Z=4, D-c=1.823 Mg.m(-3)center dot H(2)APA 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 center dot center dot center dot O, O-H center dot center dot center dot N, N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bondings. The thermogravimetric analysis was carried out to examine the thermal stability of the titled complex. CCDC: 745208.
