摘      要：One cobalt coordinated polymer with 2-fold parallel interpenetration 3D architecture based on flexible 5-（imidazol-1-ylmethyl）isophthalate （L2-） as a main ligand and 4,4＇-bipyridine （bpy） as a nitrogen-containing ancillary ligand, {[CoL（bpy）0.5（H2O）3]2}n （1）, has been obtained under hydrothermal conditions and characterized by elemental analysis, powder X-ray diffraction （PXRD）, IR spectra, Uv/vis spectra, thermal gravimetric analyses （TGA） and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group C2/c with a = 26.323（4）, b = 14.696（2）, c = 26.630（4） A, β= 157.747（4）°, V = 3901.2（1） A3, Z = 8, Mr= 435.27, Dc = 1.480 g/cm3, /t= 0.923 mm^-1, Rint = 0.0900, F（000） = 1792, the final R= 0.0722 and wR = 0.0946 for 3641 observed reflections （I 〉 2tr（/））. Complex 1 exhibits a two-fold interpenetration 3D framework. As a single net of the 2-fold interpenetration structure, the L2- anion of complex 1, as a bridging ligand, connects the Co（Ⅱ） ion to form two-dimensional layers （Co3L3）n which are further linked to build a three-dimensional framework by bpy ligand.
