Summary:The synthesis, structure and magnetic property of a new coordination network {[Co2(bcp)2(bipy)]}n (1) (H2bcp=1,3-bis(4-carboxy-phenoxy)propane and bipy=4,4′-pyridine), are reported. Compound 1 shows two identical 2D layers with 22.48.65 topology which are interpenetrated in a parallel fashion, resulting in a twofold interpenetrating motif containing polyrotaxane and polycatenane characters. Magnetic susceptibility indicated the antiferromagnetic exchange interaction. The magnetic behavior of 1 can be explained by the tilts of local distortion axes. A new compound displays twofold interpenetrating 22.48.65 topology containing polyrotaxane and polycatenane characters. The magnetic behavior of binuclear Co(II) complex can be explained by the tilts of local distortion axes. [Display omitted] ► This topology of 1 represents a new type of 6-connection topology. ► The structure contains meanwhile polyrotaxane and polycatenane characters. ► The magnetic behavior of dinuclear Co(II) complex can be explained by the tilt of local distortion axes.
