Seven novel coordination polymers, [Ln(tda)(H2O)](n)center dot 2nH(2)O [Ln = La(1), Ce(2), Pr(3), Nd(4), Eu(5), Sm(6) and Gd(7)] (H(3)tda = 1H-1,2,3-triazole-4,5-dicarboxylic acid), have been synthesized under hydrothermal conditions and characterized by elemental analysis, IR, thermogravimetric analysis (TGA), and single-crystal X-ray diffraction. Compounds 1-7 are isostructural and exhibit novel 3D chiral framework based on the linkage of chiral columns constructed from the interweaving two different kinds of helical chains. Interesting channels exist like labyrinths in the frameworks formed by interconnecting 16Ln-based cage-like building units. Furthermore, the photoluminescence property of 6 and the magnetic property of 7 have been studied.
