摘要

Two zinc arsonate coordination polymers, Zn（4-apa）·H2O （1, 4-apaH2 = 4-amino- phenylarsonatic acid） and Zn（4-apa） （2）, have been hydrothermally synthesized and characterized by elemental analysis, IR and single-crystal and powder X-ray diffraction. Crystal data for 1： monoclinic, space group C2/c with a = 23.056（5）, b = 5.4224（11）, c = 15.027（3） , β = 121.22（3）°, V = 1606.6（6） ？3, Dc = 2.468 g·cm-3, F（000） = 1168, μ = 7.122 mm-1, Z = 8, the final R = 0.0309 and wR = 0.0752 for 1763 observed reflections with I 〉 2σ（I）. For 2： monoclinic, space group P21/c with a = 8.7852（18）, b = 9.2744（19）, c = 9.752（2） , β = 103.45（3）°, V = 772.7（3）3, Dc = 2.410 g·cm-3, F（000） = 544, μ = 7.387 mm-1, Z = 4, the final R = 0.0321 and wR = 0.0741 for 1696 observed reflections with I 〉 2σ（I）. The structure of 1 shows a two-dimensional （4,4）-network composed of an inorganic ladder chain bridged by the phenyl-linkers of 4-apa ligands. Compound 2 exhibits a 3D layer-pillared framework with crb net, in which inorganic （4-82）-networks are joined by the phenyl-linkers.
