摘要 A copper（Ⅱ） coordination polymer, [Cu3（HOA）2（bpp）4]n （1, HnOA = 3,3＇,4,4＇- oxidiphthalic acid, bpp = 1,3-bis（4-pyridyl） propane）, has been hydrothermally synthesized. The crystal structure is of monoclinic, space group P21/c with a = 11.544（3）, b = 16.129（4）, c = 21.181 （6） A, β = 98.848（5）, V= 3897.0（2） A3, C84018N8H70Cu3, Mr = 1670.13, Z = 2, De = 1.423 g/cm^3, F（000） = 1722, μ = 0.887 mm^-1, R = 0.0878 and wR = 0.2583 for 8496 observed reflections （I 〉 2σ（I））. Single-crystal X-ray structural analysis reveals that 1 is a three-dimensional （3D） framework based on a two-dimensional （2D） mesomeric layer of alternating left- and fight-handed helical chains. The monodentate terminal and bidentate bridging bpp ligands in the same conformation are all encapsulated in the figure-of-eight-shaped channels, thus further stabilizing the whole three-dimensional framework.
