A new dysprosium-zinc coordination polymer {[Dy2Zn(dinic)4(H2O)8]·H2O}n 1(H2dinic = 2,5-pyridinedicaboxylic acid) has been synthesized and structurally characterized by X-ray analysis. The complex (C28H30Dy2N4O25Zn, Mr = 1212.94) crystallizes in triclinic, space group P-1 with a = 7.8911(16), b = 9.3177(19), c = 13.029(3)(A), α = 75.29(3), β = 75.04(3), γ =79.00(3)°, V = 887.1(3)(A)3, Z = 1, Dc=2.236 g/cm3,μ(MoKα) = 4.947 mm-1, F(000) = 570, the final R = 0.0345 and wR = 0.0903 for 3644 observed reflections with I＞ 2σ(I). A two-dimensional supramolecular structure is formed in 1, which was characterized by elemental analysis, IR, TG analysis, and single-crystal X-ray diffraction.
