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. 展开更多
