摘要
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 PI 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/cm^3,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.
