Abstract

A series of lanthanide-organic framework coordination polymers, {[La2(TDC)2(NO3)(H2O)4](OH)·5H2O}n (1) and [Ln(TDC)(NO3)(H2O)]n (TDC = thiophene- 2, 5- dicarboxylic acid; Ln = Nd(2), Sm(3), Eu(4), Gd(5), Tb(6), Dy(7), Ho(8), Er(9), Yb(10)) have been synthesized by solvothermal reaction and characterized by elemental analysis, FT-IR, TG analysis, single-crystal X-ray diffraction and power X-ray diffraction. The single-crystal X-ray diffraction analysis results show that 1 displays a 3-D porous framework with (3,7)-connected {410.611}{43} topology. The compounds 2–10 crystallized in the same P21/c space group and exhibits a (3,6)-connected {4.62}2{42.610.83} topology, Right-handed and left-handed helical chains coexist in the 2-D layer structure. The luminescence properties of 2–10 and the magnetic properties of 5,7,8,9 were investigated.
