A new metal-organic coordination polymer {[Nd(tci)(H2O)2]•2H2O}n (1) has been synthesized based on the flexible tricarboxylate ligand tris(2-carboxyethyl)isocyanuric acid (H3tci) and structurally characterized by single-crystal X-ray diffraction analyses, elemental analysis, infrared spectra (IR), powder X-ray diffraction (PXRD) and thermogravimetric analysis (TGA). Complex 1 crystallizes in triclinic, space group P with a = 9.1648(11), b = 9.3326(12), c = 12.440(2) Å, C12H20N3O13Nd, Mr = 558.55, V = 886.9(2) Å3, Z = 2, Dc = 2.092 g•cm-3, μ = 3.006 mm-1, F(000) = 554, 2.56<θ<25.00°, λ(MoKα) = 0.71073 Å, T = 293(2) K, the final R = 0.0662 and wR = 0.2071. X-ray diffraction analysis reveals that complex 1 is a two-dimensional layer, which is further assembled into a three-dimensional supramolecular architecture through hydrogen bonding interactions. The structure of complex 1 can be simplified as a rare 2-periodic uninodal {48•62} topology and a non-interpenetrating kgd topology. Furthermore, the thermal stability and photoluminescence property of 1 were investigated.
