| Abstract: A lanthanide coordination polymer [Eu2(Suc)0.5(BC)3(OH)2]n(H2Suc=succinic acid; HBC=benzoic acid) has been synthesized under hydrothermal conditions and was characterized by X-ray diffraction single crystal structure analysis, elemental analysis and IR spectra. The title complex crystallizes in triclinic space group P1, with a=0.681 1(2) nm, b=1.206 2(4) nm, c=1.606 3(5) nm, α=69.416(4)°, β=82.855(4)°, γ=74.869(4)°, V=1.192(7) nm3, Z=2. Infinite inorganic walls formed by lanthanide ions, three-bridging hydroxyl group, and an edge-sharing “…Eu-O-C-O-Eu…” chain, which link to each other through the carbon atoms of the succinate anions and phenyl groups of the benzoic acid ligands, leading to a two-dimensional open framework structure. The photoluminescent property and the thermogravimetric analysis of the title complex were analysized in detail. CCDC: 644783. |
