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,De=2.350 g/cm3,F(000)=4096,μ=7.136 mm-1 and Z=8.The final R 1=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.
