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

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=1.441...

description 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（I2σ（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.
