Synthesis,structure and near-infrared luminescence of a new 2D praseodymium(Ⅲ) coordination polymer

A novel coordination polymer,[Pr2(BIPA)3(H2O)2].2H2O(1)(H2BIPA=5-bromoisophthalic acid),was prepared by hydrothermal synthesis and characterized by IR spectroscopy,elemental analysis and single-crystal X-ray diffraction.The crystal was of monoclinic system,space group C2/c,with a=1.98037(14),b=1.44189(14),c=2.15281(18) nm,β=95.220(2)°,V=6.1218(9) nm3,C24H17Br3O16Pr2,Mr=1082.93,Dc= 2.350 g/cm3,F(000)=4096,μ=7.136 mm-1 and Z=8.The final R1=0.0608 and wR2=0.1371 for 5624 observed reflections(I>2σ(I)).Complex 1 featured an interesting 2D layer containing {Pr2(CO2)3}n right-handed and left-handed helical chains.Furthermore,hydrogen bonds linked the adjacent 2D layers to form a 3D supramolecular framework.Moreover,the near-infrared luminescent properties of 1 were also investigated in the solid state.     

Synthesis, structure and photoluminescent properties of a new Eu(Ⅲ) complex with 5-bromoisophthalic acid

The self-assembly of 5-bromoisophthalic acid (H2BIPA) with Eu(NO3)3·6H2O under the hydrothermal conditions gave a 3D coordination polymer, Eu2(BIPA)3(CH3CH2OH) (1), which was characterized by elemental analysis, IR and single-crystal X-ray diffraction. Complex 1 displayed an unusual three-dimensional network of a rare (4,6)-connected (48.66.8)2(44.62)2(42.84) topology, which was different from Eu2(BDC)3(H2O)2 (BDC=isophthalate), because the -Br substituent of the isophthalate resulted in the different electronic effects and the steric hindrance to change the coordination modes of carboxylate groups in the assembled process. Moreover, the luminescent properties of 1 were also investigated in the solid state.

Lanthanum(Ⅲ) sorption studies on poly[dibenzo-18-crown-6] and its separation from uranium(Ⅵ) and thorium(Ⅳ) in L-valine medium

The sorption study of La(Ⅲ) was carried out on poly[dibenzo-18-crown-6] and L-valine medium. The quantitative adsorption of La(Ⅲ) was found at 1x10-2 to 1x10-5 mol/L L-valine. The various eluting agents were found efficient eluents for La(Ⅲ). The capacity of crown polymer for La(Ⅲ) was found to be 0.43 ±0.01 mmol/g. The tolerance limit of various cations and anions for La(Ⅲ) was determined.La(Ⅲ) was quantitatively separated from other metal ions in binary as well as multicomponont mixtures. The study was extended to sequen-tial separation of La(Ⅲ), U(Ⅵ) and Th(Ⅳ). The good separation yields were obtained and had good reproducibility (±2%). The method in-corporated the determination of La(Ⅲ) in real sample. The method was simple, rapid and selective.
